Abstract

Control of magnetism by an applied electric field is a desirable technique for the functionalization of magnetic materials. Motivated by recent experiments, we study the electric field control of the interfacial magnetism of ${\mathrm{CaRuO}}_{3}/{\mathrm{CaMnO}}_{3}$ (CRO/CMO) (001), a prototype interface between a nonmagnetic metal and an antiferromagnetic insulator. Even without the electric field, the interfacial CMO layer acquires a ferromagnetic moment due to a spin-canted state, caused by the Anderson-Hasegawa double exchange (DEX) between the Mn moments and the leaked electrons from the CRO side. An electric field would alter the carrier density at the interface, leading to the possibility of controlling the magnetism, since DEX is sensitive to the carrier density. We study this effect quantitatively using density-functional calculations in the slab geometry. We find a textbook-like dielectric screening of the electric field, which introduces polarization charges at the interfaces and the surfaces. The extra charge at the interface enhances the ferromagnetism via the DEX interaction, while away from the interface the original antiferromagnetic (AFM) state of the Mn layers remains unchanged. The effect could have potential application in spintronics devices.

Abstract

The orbital Hall effect (OHE) is the transverse flow of orbital moment in a solid in response to an applied electric field, analogous to the flow of spin moment in the spin Hall effect (SHE). Although the effect has not been directly observed, there is ample indirect evidence for its existence in a number of experiments. Here, we show that the OHE is enhanced in solids with broken inversion symmetry, which may be more suitable to observe the effect. The mechanism of the OHE is fundamentally different in solids with inversion symmetry, where the orbital moment is quenched in the Brillouin zone (BZ), from that in a solid with broken inversion symmetry, where an intrinsic orbital moment is already present, the motion of which under the applied electric field could lead to a robust OHE. Using a tight-binding model Hamiltonian of a simple cubic lattice with two atoms in the unit cell, we study the effect of the inversion symmetry breaking on the OHE. We show that with the increase in the strength of the broken symmetry, the magnitude of the intrinsic orbital moment in the Brillouin zone increases. This, in turn, enhances the orbital Hall conductivity, in particular, the part that is directly proportional to the orbital moment in the BZ, which we call the ``noncentrosymmetric contribution.'' If the spin-orbit coupling is present, which couples the orbital and spin moments, the OHE leads to the SHE, which also becomes enhanced by the broken inversion symmetry. Our work has important implications for experimenters, suggesting that noncentrosymmetric solids may be more suitable for direct observation of the OHE.

Abstract

Orbital Hall effect (OHE) is the phenomenon of transverse flow of orbital moment in presence of an applied electric field. Solids with broken inversion symmetry are expected to exhibit a strong OHE due to the presence of an intrinsic orbital moment at individual momentum points in the Brillouin zone, which in presence of an applied electric field, flows in different directions causing a net orbital Hall current. Here we provide a comprehensive understanding of the effect and its tunability in the monolayer 2D transition metal dichalcogenides (TMDCs). Both metallic and insulating TMDCs are investigated from full density-functional calculations, effective $d$-band tight-binding models, as well as a minimal four-band model for the valley points that captures the key physics of the system. For the tuning of the OHE, we examine the role of hole doping as well as the change in the band parameters, which, e. g., can be controlled by strain. We demonstrate that the OHE is a more fundamental effect than the spin Hall effect (SHE), with the momentum-space orbital moments inducing a spin moment in the presence of the spin-orbit coupling, leading to the SHE. The physics of the OHE, described here, is relevant for 2D materials with broken inversion symmetry in general, even beyond the TMDCs, providing a broad platform for future research., Comment: 20 pages, 15 figures

Abstract

Carrying information using generation and detection of the orbital current, instead of the spin current, is an emerging field of research, where the orbital Hall effect (OHE) is an important ingredient. Here, we propose a mechanism of the OHE that occurs in noncentrosymmetric materials. We show that the broken inversion symmetry in the two-dimensional transition metal dichalcogenides (TMDCs) causes a robust orbital moment, which flows in different directions due to the opposite Berry curvatures under an applied electric field, leading to a large OHE. This is in complete contrast to the inversion-symmetric systems, where the orbital moment is induced only by the external electric field. We show that the valley-orbital locking as well as the OHE both appear even in the absence of the spin-orbit coupling. The nonzero spin-orbit coupling leads to the well-known valley-spin locking and the spin Hall effect, which we find to be weak, making the TMDCs particularly suitable for direct observation of the OHE, with potential application in orbitronics.

Abstract

Nodal line semimetals with symmetry protected band structure offer a platform for the investigation of a number of emerging quantum phenomena. Using first-principles calculation combined with symmetry analysis, we show that ${\mathrm{Ba}}_{3}{\mathrm{TiIr}}_{2}{\mathrm{O}}_{9}$ hosts a Dirac nodal line (DNL) along the $A\text{\ensuremath{-}}L$ direction of the Brillouin zone, protected by the glide reflection symmetry. In the presence of the spin-orbit coupling, even though the DNL along the $A\text{\ensuremath{-}}L$ direction is protected, DNLs along other directions as well as multiple nodal loops present in the system gap out. The gapped out Dirac nodal loops act as a source of spin Berry curvature, resulting in a large spin Hall conductivity ($\ensuremath{\approx}300$ $\frac{\ensuremath{\hbar}}{e}\phantom{\rule{4pt}{0ex}}{\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}1}{\phantom{\rule{0.16em}{0ex}}\mathrm{cm}}^{\ensuremath{-}1}$). This suggests the possible application of the material as a spin current detector.

Abstract

The electronic structure and the anomalous Hall effect (AHE) at the recently grown $3d\text{\ensuremath{-}}5d$ superlattice structure ${({\mathrm{SrMnO}}_{3})}_{1}/{({\mathrm{SrIrO}}_{3})}_{1}$ are investigated theoretically using model and density-functional calculations. The observed ferromagnetism for the SMO layer, which becomes electron doped because of the charge transfer across the interface, is explained to be due to the Anderson-Hasegawa double exchange, while the SIO side becomes ferromagnetic due to the proximity effect and the Nagaoka physics of a hole-doped system. The broken time-reversal symmetry and the strong spin-orbit coupling in SIO provide the two essential ingredients for the AHE, which we describe within a square lattice model of $d$-orbitals relevant for the present structure. The model correctly predicts the order of magnitude of the anomalous Hall conductivity (AHC), which is computed using the Kubo formula. The density-functional results for the AHC are in good agreement with the experiments.

Abstract

Effects of the structural distortion associated with the ${\mathrm{OsO}}_{6}$ octahedral rotation and tilting on the electronic band structure and magnetic anisotropy energy for the $5{d}^{3}$ compound ${\mathrm{NaOsO}}_{3}$ are investigated using the density functional theory (DFT) and within a three-orbital model. Comparison of the essential features of the DFT band structures with the three-orbital model for both the undistorted and distorted structures provides insight into the orbital and directional asymmetry in the electron hopping terms resulting from the structural distortion. The orbital mixing terms obtained in the transformed hopping Hamiltonian resulting from the octahedral rotations are shown to account for the fine features in the DFT band structure. Staggered magnetization and the magnetic character of states near the Fermi energy indicate weak coupling behavior.

Abstract

Chiral order in magnetic structures is currently an area of considerable interest and leads to skyrmion structures and domain walls with certain chirality. The chiral structure originates from the Dzyaloshinskii-Moriya interaction caused by broken inversion symmetry and the spin-orbit interaction. In addition to the Rashba or Dresselhaus interactions, there may also exist substantial spin polarization in magnetic thin films. Here, we study the exchange interaction between two localized magnetic moments in the spin-polarized electron gas with both Rashba and Dresselhaus spin-orbit interaction present. Analytical expressions are found in certain limits in addition to what is known in the literature. The stability of the Bloch and N\'eel domain walls in magnetic thin films is discussed in light of our results.

Abstract

Motivated by the current interest in the understanding of the Mott insulators away from half filling, observed in many perovskite oxides, we study the Mott metal-insulator transition (MIT) in the doped Hubbard-Holstein model using the Hatree-Fock mean field theory. The Hubbard-Holstein model is the simplest model containing both the Coulomb and the electron-lattice interactions, which are important ingredients in the physics of the perovskite oxides. In contrast to the half-filled Hubbard model, which always results in a single phase (either metallic or insulating), our results show that away from half-filling, a mixed phase of metallic and insulating regions occur. As the dopant concentration is increased, the metallic part progressively grows in volume, until it exceeds the percolation threshold, leading to percolative conduction. This happens above a critical dopant concentration $\delta_c$, which, depending on the strength of the electron-lattice interaction, can be a significant fraction of unity. This means that the material could be insulating even for a substantial amount of doping, in contrast to the expectation that doped holes would destroy the insulating behavior of the half-filled Hubbard model. Our theory provides a framework for the understanding of the density-driven metal-insulator transition observed in many complex oxides.

Abstract

We present a new method for describing the electronic structure of graphene, by treating the honeycomb lattice as an arrangement of crisscrossing one-dimensional quantum wires. The electrons travel as free particles along the wires and interfere at the three-way junctions formed by the carbon atoms. The approach produces the linearly dispersive Dirac band structure as well as the chiral pseudo-spin-wave functions. When vacancies are incorporated, the model reproduces the well known zero mode states.

Abstract

The metallic helimagnet MnSi has been found to exhibit skyrmionic spin textures when subjected to magnetic fields at low temperatures. The Dzyaloshinskii-Moriya (DM) interaction plays a key role in stabilizing the skyrmion state. With the help of first-principles calculations, crystal field theory, and a tight-binding model we study the electronic structure and the origin of the DM interaction in the B20 phase of MnSi. The strength of the $\stackrel{P\vec}{D}$ parameter is determined by the magnitude of the spin-orbit interaction and the degree of orbital mixing, induced by the symmetry-breaking distortions in the B20 phase. Our calculations suggest strong coupling between Mn-$d$ and Si-$p$ states, which is consistent with a mixed valence ground state $|{d}^{7\ensuremath{-}x}{p}^{2+x}\ensuremath{\rangle}$ configuration. Consistent with previous calculations, we find that DFT+U leads to the experimental magnetic moment of $0.4\phantom{\rule{0.28em}{0ex}}{\ensuremath{\mu}}_{B}$, which redistributes electrons between the majority and minority spin channels. We derive the magnetic interaction parameters $J$ and $\stackrel{P\vec}{D}$ for Mn-Si-Mn superexchange paths using Moriya's theory assuming the interaction to be mediated by ${e}_{g}$ electrons near the Fermi level. Using parameters from our calculations, we get reasonable agreement with the observations.

Abstract

We study the mechanism of intermediate energy heavy-ion collisions in a picture of tripartition of the total system, using the framework of statistical simultaneous multifragmentation model taking into account the entrance channel characteristics, with no other parameter except density. The relative excitations of the three parts and their contributions to the physical observables such as mean multiplicity for different fragments and total fragment multiplicity are shown as functions of entrance channel properties; namely, the impact parameter, the bombarding energy, and the mass of projectile and target nuclei. As an application we apply the model to describe the data on {sup 40}Ar+{sup 40}Ca and {sup 40}Ar+{sup 197}Au reaction with incident energy varying from 42 to 137 MeV/nucleon, and the intermediate mass fragment production in the {sup 197}Au+{sup 197}Au reaction with incident energies 100 and 400 MeV/nucleon. The importance of the contributions from the spectator parts is clearly demonstrated. It is also shown that the role of the interfragment interaction is important up to bombarding energy 100 MeV/nucleon and a temperature of about 10 MeV. {copyright} {ital 1997} {ital The American Physical Society}

Abstract

We present a systematic method for developing a five band Hamiltonian for the metal d orbitals that can be used to study the effect of electric and magnetic fields on multilayer MX2 (M=Mo,W and X=S,Se) systems. On a hexagonal lattice of d orbitals, the broken inversion symmetry of the monolayers is incorporated via fictitious s orbitals at the chalcogenide sites. A tight-binding Hamiltonian is constructed and then downfolded to get effective d orbital overlap parameters using quasidegenerate perturbation theory. The steps to incorporate the effects of multiple layers, external electric and magnetic fields are also detailed. We find that an electric field produces a linear-k Rashba splitting around the Γ point, while a magnetic field removes the valley pseudospin degeneracy at the ±K points. Lastly, our model provides a simple tool to understand the recent experiments on electric and magnetic control of valley pseudospin in monolayer dichalcogendies.

Abstract

Based on the fireball model and the spectator-participant picture, a statistical simultaneous multifragmentation model is developed for heavy ion induced reactions, with the entrance channel characteristics taken into account. This model has the density as the only parameter and it predicts the excitation energy, the temperature, and the frgmentation cross section, etc., once the incident energy, the projectile, and the target nuclei are specified. As a first application, it has been applied to the central collision data taken at National Superconducting Cyclotron Laboratory on the {sup 40}Ar+{sup 45}Sc reaction at incident energies ranging from 35 to 115 MeV/{ital A}. The study brings out the similarity in the characteristics of high energy proton induced and medium energy heavy ion induced reactions. It is observed that with rise of bombarding energy, the onset of simultaneous multifragmentation occurs at some energy between 50 and 60 MeV/{ital A}. {copyright} {ital 1996 The American Physical Society.}

Abstract

We show that the Rashba spin-orbit interaction in $d$ electron solids, which originates from the broken inversion symmetry at surfaces or interfaces, is strongly dependent on the orbital characters of the bands involved. This is studied by developing a tight-binding model in the presence of a uniform perpendicular electric field and spin-orbit coupling. We argue that for valence electrons, the spin-orbit coupling strength scales only as the square of the atomic number. The electric field distorts the $d$ orbitals through the admixture of $p$ and $f$ states and also introduces intersite overlap parameters. Expressions for Rashba coefficients for the bands are obtained in both weak and strong spin-orbit interaction limits and are shown to be orbital dependent. The results are compared with first-principles calculations for model systems, showing good agreement. Our study demonstrates the orbital-dependent gate control of the Rashba effect for the purposes of oxide electronics.

Abstract

Using density-functional methods, we study the electronic structure of ${\mathrm{Ba}}_{3}\mathrm{Cu}{\mathrm{Sb}}_{2}{\mathrm{O}}_{9}$, a candidate material for the quantum spin liquid behavior. We study both the triangular lattice as well as the recently proposed hexagonal lattice structures with flipped Cu-Sb dumbbells. The band structure near the Fermi energy is described very well by a tight-binding Hamiltonian involving the Cu (${e}_{g}$) orbitals, confirming their central role in the physics of the problem. A minimal tight-binding Hamiltonian for the triangular structure is presented. The Cu (${d}^{9}$) ions (a single ${e}_{g}$ hole in the band structure) present in the compound are expected to be Jahn-Teller centers, while the nature of the Jahn-Teller distortions in this material is still under debate. Solving a simple model by exact diagonalization, we show that electronic correlation effects in general enhance the tendency towards a Jahn-Teller distortion by reducing the kinetic energy due to correlation effects. Our density-functional calculations do indeed show a significant Jahn-Teller distortion of the $\mathrm{Cu}{\mathrm{O}}_{6}$ octahedra when we include the correlation effects within the Coulomb-corrected GGA+U method, so that the Jahn-Teller effect is correlation driven. We argue for the presence of a random static Jahn-Teller distortion in the hexagonal structure rather than a dynamical one because of the broken octahedral symmetry around the $\mathrm{Cu}{\mathrm{O}}_{6}$ octahedra and the potential fluctuations inherently present in the system caused by a significant disorder, which is believed to be present, in particular, due to the flipped Cu-Sb dumbbells.

Abstract

We show that the Rashba effect at the polar perovskite surfaces and interfaces can be tuned by manipulating the two-dimensional electron gas (2DEG) by an applied electric field, using it to draw the 2DEG out to the surface or push it deeper into the bulk, thereby controlling the surface-sensitive phenomenon. These ideas are illustrated by a comprehensive density-functional study of the recently-discovered polar KTaO$_3$ surface. Analytical results obtained with a tight-binding model unravel the interplay between the various factors affecting the Rashba effect such as the strength of the spin-orbit interaction and the surface-induced asymmetry. Our work helps interpret the recent experiments on the KTaO$_3$ surface as well as the SrTiO$_3$/LaAlO$_3$ interface., Comment: 5 pages, 6 figures, Supplementary material

The measurement is based on a $5.9{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected by the Belle detector at KEKB. The proper-time difference distributions for same-sign and opposite-sign dilepton events are simultaneously fitted to an expression containing $\ensuremath{\Delta}{m}_{d}$ as a free parameter. Using both muons and electrons, we obtain $\ensuremath{\Delta}{m}_{d}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.463\ifmmode\pm\else\textpm\fi{}0.008(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.016(\mathrm{syst}){\mathrm{ps}}^{\ensuremath{-}1}$. This is the first determination of $\ensuremath{\Delta}{m}_{d}$ from time evolution measurements at the $\ensuremath{\Upsilon}(4S)$. We also place limits on possible $\mathrm{CPT}$ violations.

Abstract

We present a measurement of the standard model $\mathrm{CP}$ violation parameter $\mathrm{sin}2{\ensuremath{\varphi}}_{1}$ (also known as $\mathrm{sin}2\ensuremath{\beta}$) based on a $10.5{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric ${e}^{+}{e}^{\ensuremath{-}}$ collider. One neutral $B$ meson is reconstructed in the $J/\ensuremath{\psi}{K}_{S}$, $\ensuremath{\psi}(2S){K}_{S}$, ${\ensuremath{\chi}}_{c1}{K}_{S}$, ${\ensuremath{\eta}}_{c}{K}_{S}$, $J/\ensuremath{\psi}{K}_{L}$, or $J/\ensuremath{\psi}{\ensuremath{\pi}}^{0}$ $\mathrm{CP}$-eigenstate decay channel and the flavor of the accompanying $B$ meson is identified from its charged particle decay products. From the asymmetry in the distribution of the time interval between the two $B$-meson decay points, we determine $\mathrm{sin}2{\ensuremath{\varphi}}_{1}{\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.58}_{\ensuremath{-}0.34}^{+0.32}(\mathrm{stat}{)}_{\ensuremath{-}0.10}^{+0.09}(\mathrm{syst})$.

Abstract

We describe the ferromagnetism in the manganese pyrochlores, such as ${\mathrm{Tl}}_{2}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7}$ and ${\mathrm{Sc}}_{2}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7},$ in terms of the interplay between superexchange, Zener double exchange, and indirect exchange, the first being antiferromagnetic (AF) while the last two are ferromagnetic. The tendency towards the antiferroalignment of the localized Mn spins is significantly weakened due to (i) the presence of spin frustration in the Mn sublattice and (ii) the large bend in the Mn-O-Mn bond, which reduces the magnitude of the AF superexchange. This helps the ferromagnetic interaction terms, viz., the indirect exchange and the Zener double exchange, to dominate. The indirect exchange on the Mn-O-Mn bond, which is modeled by a coupling of the O $2p$ electrons to the conduction-band states, produces a weak ferromagnetism in the insulating pyrochlores. In the metallic pyrochlores, the indirect exchange is also present, but it is now supplemented by the Zener double exchange, making the ferromagnetism more robust, as indicated from a higher value of the Curie temperature ${T}_{c}.$ Density-functional calculations for the metallic ${\mathrm{Tl}}_{2}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7}$ pyrochlore, show the itinerant Zener carriers mediating double-exchange to be electrons in the ${\ensuremath{\Gamma}}_{1}$ minority spin band crossing the Fermi energy, with predominantly Mn $3d,$ Tl $6s,$ and O $2p$ characters. These Zener carriers move in a lattice of localized Mn ${t}_{2g}$ spins, with the carrier spins aligned antiparallel to the localized spins.

Abstract

The coupled magnetic and charge-order transition observed in the manganites of the type R1-xMxMnO3 near half filling (x similar or equal to 1/2) is shown to be the result of the interplay between the double-exchange, superexchange, and the Coulomb interaction terms in an electronic Hamiltonian. At half tilling and temperature T=0 we find, as we increase the strength of the extended-Hubbard repulsion, a first-order transition from a charge-nonordered ferromagnetic metal (FN) to a charge-ordered antiferromagnetic and insulating (AFO) ground state. The AFO-FN transition is also obtained by increasing T: however, a small degree of charge order remains ill the ferromagnetic phase. The charge-ordered state also ''melts,'' as observed, on the application of a magnetic field, which causes a rapid drop in the transition temperature. Qualitative differences ill behavior between members of the manganite series can be understood in terms of small variations in the interaction parameters.

Abstract

We study the dynamics of flux penetration and vortex pinning in a type-II superconductor by numerical simulations with forces appropriate in the London regime. Straight vortex lines at zero temperature are studied in a slab geometry, and, unlike previous studies, full account is taken of the dynamical penetration of the flux lines across the surface under the application of an external magnetic field. Our simulation produces flux penetration in the sample beyond H{sub c1} as expected, with the flux lines forming an Abrikosov lattice in the absence of the pinning centers. The pinning centers impede flux penetration into the bulk and the resulting critical current decreases with increasing vortex density roughly in agreement with the modified Bean{close_quote}s model. {copyright} {ital 1997} {ital The American Physical Society}

Abstract

The existence of the canted ~noncollinear! spin order in the double-exchange magnets is examined by solving a model Hamiltonian using a combination of the Hartree-Fock approximation and an exact diagonalization scheme using the Lanczos method. It is shown that the tendency for the canted spin order depends significantly on the electronic parameters and that the double-exchange mechanism does not always lead to a canted magnetic state, even for small carrier concentration. @S0163-1829~97!00506-7#

Abstract

The e{sup +}e{sup -}{yields}pp cross section is determined over a range of pp masses, from threshold to 4.5 GeV/c{sup 2}, by studying the e{sup +}e{sup -}{yields}pp{gamma} process. The data set corresponds to an integrated luminosity of 232 fb{sup -1}, collected with the BABAR detector at the PEP-II storage ring, at an e{sup +}e{sup -} center-of-mass energy of 10.6 GeV. The mass dependence of the ratio of electric and magnetic form factors, G{sub E}/G{sub M}, is measured for pp masses below 3 GeV/c{sup 2}; its value is found to be significantly larger than 1 for masses up to 2.2 GeV/c{sup 2}. We also measure J/{psi}{yields}pp and {psi}(2S){yields}pp branching fractions and set an upper limit on Y(4260){yields}pp production and decay.

Abstract

We study the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between two contact magnetic impurities placed on bilayer graphene (BLG). We compute the interaction mediated by the carriers of the pristine and biased BLG as well as the conduction electrons of the doped system. The results are obtained from the linear-response expression for the susceptibility written in terms of the integral over lattice Green's functions. For the unbiased system, we obtain some analytical expressions in terms of the Meijer G-functions, which consist of the product of two oscillatory terms, one coming from the interference between the two Dirac points and the second coming from the Fermi momentum. In particular, for the undoped BLG, the system exhibits the RKKY interaction commensurate with its bipartite nature as expected from the particle-hole symmetry of the system. Furthermore, we explore a beating pattern of oscillations of the RKKY interaction in a highly doped BLG system within the four-band continuum model. Besides, we discuss the discrepancy between the short-range RKKY interaction calculated from the two-band model and that obtained from the four-band continuum model. The final results for the applied gate voltage are obtained numerically and are fitted with the functional forms based on the results for the unbiased case. In this case, we show that the long-range behavior is scaled with a momentum that depends on Fermi energy and gate voltage, allowing the possibility of tuning of the RKKY interaction by gate voltage., 13 pages, 6 figures

As compared to the energy expansion, it is found that, in the pure bulk mode of density vibration, the LDM expansion of $K_A$ shows an anomalous convergence behaviour due to {\it pair \ effect}. A least squares fit analysis is done to estimate the minimum error, one would expect even with synthetic data due to the inherent nature of the LDM expansion of $K_A$ as well as the narrow range of accessible mass number $A$, in the values of the various coefficients. The dependence of the higher-order coefficients like curvature and Gauss curvature on the coupling $\beta_c$ between the bulk and surface parts of the monopole vibrations is analytically studied. It is shown that the $K_A -$ expansion including the dynamical effect ( $A-$ dependence of $\beta_c$ ) shows an `up-turn' behaviour below mass number about 120, suggesting the inapplicability of the LDM expansion of $K_A$ over this mass region., Comment: 30 latex pages, five figures available on request ( to appear in Phy.

Abstract

Starting with a two-body effective nucleon-nucleon interaction, it is shown that the infinite nuclear matter model of atomic nuclei is more appropriate than the conventional Bethe-Weizsacker like mass formulae to extract saturation properties of nuclear matter from nuclear masses. In particular, the saturation density thus obtained agrees with that of electron scattering data and the Hartree-Fock calculations. For the first time using nuclear mass formula, the radius constant $r_0$=1.138 fm and binding energy per nucleon $a_v$ = -16.11 MeV, corresponding to the infinite nuclear matter, are consistently obtained from the same source. An important offshoot of this study is the determination of nuclear matter incompressibility $K_{\infty}$ to be 288$\pm$ 28 MeV using the same source of nuclear masses as input., 14 latex pages, five figures available on request ( to appear in Phy.

Abstract

We report results from an updated study of the suppressed decays ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}D{K}^{\ensuremath{-}}$ and ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{*}{K}^{\ensuremath{-}}$ followed by $D\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, where ${D}^{(*)}$ indicates a ${D}^{(*)0}$ or a ${\overline{D}}^{(*)0}$ meson, and ${D}^{*}\ensuremath{\rightarrow}D{\ensuremath{\pi}}^{0}$ or ${D}^{*}\ensuremath{\rightarrow}D\ensuremath{\gamma}$. These decays are sensitive to the Cabibbo-Kobayashi-Maskawa unitarity triangle angle $\ensuremath{\gamma}$ due to interference between the $b\ensuremath{\rightarrow}c$ transition ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{(*)0}{K}^{\ensuremath{-}}$ followed by the doubly Cabibbo-suppressed decay ${D}^{0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, and the $b\ensuremath{\rightarrow}u$ transition ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\overline{D}}^{(*)0}{K}^{\ensuremath{-}}$ followed by the Cabibbo-favored decay ${\overline{D}}^{0}\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. We also report an analysis of the decay ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{(*)}{\ensuremath{\pi}}^{\ensuremath{-}}$ with the $D$ decaying into the doubly Cabibbo-suppressed mode $D\ensuremath{\rightarrow}{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. Our results are based on $467\ifmmode\times\else\texttimes\fi{}\phantom{\rule{0ex}{0ex}}{10}^{6}$ $\ensuremath{\Upsilon}(4S)\ensuremath{\rightarrow}B\overline{B}$ decays collected with the BABAR detector at SLAC. We measure the ratios ${\mathcal{R}}^{(*)}$ of the suppressed ($[{K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}{]}_{D}{K}^{\ensuremath{-}}/{\ensuremath{\pi}}^{\ensuremath{-}}$) to favored ($[{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{]}_{D}{K}^{\ensuremath{-}}/{\ensuremath{\pi}}^{\ensuremath{-}}$) branching fractions as well as the $CP$ asymmetries ${\mathcal{A}}^{(*)}$ of those modes. We see indications of signals for the ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}D{K}^{\ensuremath{-}}$ and ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}_{D{\ensuremath{\pi}}^{0}}^{*}{K}^{\ensuremath{-}}$ suppressed modes, with statistical significances of 2.1 and $2.2\ensuremath{\sigma}$, respectively, and we measure: ${\mathcal{R}}_{DK}=(1.1\ifmmode\pm\else\textpm\fi{}0.6\ifmmode\pm\else\textpm\fi{}0.2)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}2},\phantom{\rule{2em}{0ex}}{\mathcal{A}}_{DK}=\ensuremath{-}0.86\ifmmode\pm\else\textpm\fi{}{0.47}_{\ensuremath{-}0.16}^{+0.12}$, ${\mathcal{R}}_{(D{\ensuremath{\pi}}^{0})K}^{*}=(1.8\ifmmode\pm\else\textpm\fi{}0.9\ifmmode\pm\else\textpm\fi{}\phantom{\rule{0ex}{0ex}}0.4)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}2},\phantom{\rule{2em}{0ex}}{\mathcal{A}}_{(D{\ensuremath{\pi}}^{0})K}^{*}=+0.77\ifmmode\pm\else\textpm\fi{}0.35\ifmmode\pm\else\textpm\fi{}0.12,\phantom{\rule{2em}{0ex}}{\mathcal{R}}_{(D\ensuremath{\gamma})K}^{*}=(1.3\ifmmode\pm\else\textpm\fi{}1.4\ifmmode\pm\else\textpm\fi{}0.8)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}2},{\mathcal{A}}_{(D\ensuremath{\gamma})K}^{*}=+0.36\phantom{\rule{0ex}{0ex}}\ifmmode\pm\else\textpm\fi{}{0.94}_{\ensuremath{-}0.41}^{+0.25}$, where the first uncertainty is statistical and the second is systematic. We use a frequentist approach to obtain the magnitude of the ratio ${r}_{B}\ensuremath{\equiv}|A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\overline{D}}^{0}{K}^{\ensuremath{-}})/A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{0}{K}^{\ensuremath{-}})|=({9.5}_{\ensuremath{-}4.1}^{+5.1})%$, with ${r}_{B}l16.7%$ at 90% confidence level. In the case of ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{*}{K}^{\ensuremath{-}}$ we find ${r}_{B}^{*}\ensuremath{\equiv}|A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{\overline{D}}^{*0}{K}^{\ensuremath{-}})/A({B}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}^{*0}{K}^{\ensuremath{-}})|=({9.6}_{\ensuremath{-}5.1}^{+3.5})%$, with ${r}_{B}^{*}l15.0%$ at 90% confidence level.

Abstract

A search for pair production of second-generation scalar leptoquarks in the final state with two muons and two jets is performed using proton-proton collision data at sqrt(s) = 7 TeV collected by the CMS detector at the LHC. The data sample used corresponds to an integrated luminosity of 34 inverse picobarns. The number of observed events is in good agreement with the predictions from the standard model processes. An upper limit is set on the second-generation leptoquark cross section times beta^2 as a function of the leptoquark mass, and leptoquarks with masses below 394 GeV are excluded at a 95% confidence level for beta = 1, where beta is the leptoquark branching fraction into a muon and a quark. These limits are the most stringent to date.
