The liquid-gas phase transition of asymmetric nuclear matter is studied within the relativistic mean-field model with nonlinear isoscalar-isovector coupling. The density dependence of symmetry energy constrained from the measured neutron skin thickness of finite nuclei has also been used in the investigation. It is found that several features of liquid-gas phase transition, such as, liquid-gas coexistence region, critical values of pressure and isospin asymmetry and maximal isospin asymmetry increase with the softness of density dependence of symmetry energy. It is also found that the critical temperature is higher for softer symmetry energy. [ABSTRACT FROM AUTHOR]

Nuclear reactions are one of the most powerful probes to study the properties of nuclei, in particular nuclei at the limits of stability. Reactions also play an important role in astrophysics and other applications. In order to extract useful information from reaction measurements, experiment goes hand-in-hand with reaction theory. While the last five decades have provided very good qualitative understanding of the processes, the challenge in the field of reaction theory is to have a grasp on the systematic uncertainties, such that predictions can be truly quantitative. Here, we provide some examples of ongoing efforts aimed at advancing the theory for (d; p) reactions and reducing the associated uncertainties. We present the status of using the 86Kr(d, p) reaction and the combined method to control the uncertainties introduced by the overlap function. We also discuss the ambiguities of using only data to constrain the optical potential and will show recent results on the role of non-locality in transfer reactions. [ABSTRACT FROM AUTHOR]

Three- and higher-body forces enter naturally in effective field theories for strongly interacting quantum systems. We focus on the effect of three-body forces in systems close to the unitary limit and discuss applications in ultracold atoms and halo nuclei. [ABSTRACT FROM AUTHOR]

A statistical theory incorporating temperature, angular momentum and deformation degrees of freedom for complex nuclear system has been developed. An investigation for nuclear specific heat as a function of temperature and angular momentum is provided. The occurrence of a peak structure in the specific heat at temperatures of the order of 2.0-3.0 MeV confirms the phase transitions for seven even--even 2s-1d shell nuclei. [ABSTRACT FROM AUTHOR]

Total cross-sections of the halo nuclei in both the zero- and the finite-ranges are calculated at energy range of 25-800MeV/n, by using the carbon nuclei as a probe. The calculations are based on the Optical Limit Approximation (OLA) of the Glauber theory and are done for Li, Be and B isotopes using the finite and the zero range interactions. We found that the total cross-sections depend slightly on the nuclear density. On the other hand, there is a discrepancy between the calculated results of both ranges in the surface region of the reaction probability. The theoretical results for the zero- and the finite-range are compared with experimental data. We found that the zero-range predictions are consistent with experimental data more than the finite-range. [ABSTRACT FROM AUTHOR]

The volume and surface symmetry parts of the nuclear symmetry energy and other coefficients of the liquid droplet model are determined from the measured atomic masses by the maximum likelihood estimator. The volume symmetry energy coefficient extracted from finite nuclei provides a constraint on the nuclear symmetry energy. This approach also yields the neutron skin of a finite nucleus through its relationship with the volume and surface symmetry terms and the Coulomb energy coefficient. The description of nuclear matter from the isoscalar and isovector components of the density dependent M3Y effective interaction provides a value of the symmetry energy that is consistent with the empirical value of the symmetry energy extracted from measured atomic masses and with other modern theoretical descriptions of nuclear matter.

The medium dependence of nuclear interactions is described by an effective Lagrangian characterized by density dependent meson nucleon couplings. The density dependence of the coupling parameters of the σ, ω, δ, and ρ mesons is deduced by reproducing the nucleon self-energy resulting from the relativistic Brueckner-Hartree-Fock approach at each density for symmetric and asymmetric nuclear matter. The inclusion of the density dependent isovector mesons couplings, δ and ρ, affects the density and charge distributions of finite nuclei. The results are discussed and compared with experimental data and with results from similar approaches. [ABSTRACT FROM AUTHOR]

Role of the isospin asymmetry in nuclei and neutron stars, with an emphasis on the density dependence of the nuclear symmetry energy, is discussed. The symmetry energy is obtained using the isoscalar as well as isovector components of the density dependent M3Y effective interaction. The constants of density dependence of the effective interaction are obtained by reproducing the saturation energy per nucleon and the saturation density of spin and isospin symmetric cold infinite nuclear matter. Implications for the density dependence of the symmetry energy in case of a neutron star are discussed, and also possible constraints on the density dependence obtained from finite nuclei are compared.
