Abstract

Physics The Hubbard model describes the physics of interacting particles on a lattice and is thought to contain elements essential to the superconductivity of the cuprates. Despite its apparent simplicity, solving the Hubbard model remains extremely challenging, especially at finite concentrations of hole dopants and intermediate temperatures. Wietek et al. used the minimally entangled typical thermal states (METTS) method to calculate the structural factors and thermodynamic properties for the two-dimensional Hubbard model with strong correlations at a finite doping and for a range of temperatures. The researchers found that a stripe order formed at low temperatures, whereas at higher temperatures, a phase resembling the experimentally observed pseudogap state took over. Phys. Rev.

Abstract

Magnetism Spin ices, magnetic systems in which local spins respect the so-called ice rules, can occur in natural materials or be engineered in patterned arrays. King et al. used superconducting qubits to implement a two-dimensional artificial spin ice. By changing the strength and ratio of spin couplings, the researchers were able to access a variety of ground states. Arranging the boundary spins in an antiferromagnetic configuration and then flipping one of those spins generated a magnetic monopole in the system's interior. Science , abe2824, this issue p.

Abstract

Spin Liquids Although the material α-ruthenium chloride exhibits some of the physics associated with Kitaev spin liquids, it is not a perfect representation of this model. Yokoi et al. probed the limits of the Kitaev description by studying the thermal Hall response in this material. Applying an external magnetic field both in the plane of the sample and at an angle to it, the researchers observed a half-integer quantization of the thermal Hall signal. The findings suggest the formation of a topological state consistent with the Kitaev model. Science , aay5551, this issue p. [568][1] [1]: /lookup/doi/10.1126/science.aay5551

Abstract

Oxide Electronics Vanadium dioxide is known to have a coupled structural and electronic transition that can be accessed through light, thermal, or electrical excitation. Ultrafast optical studies of this insulator-to-metal transition indicate that it is mediated by the formation of a transient metallic phase that retains the structure of the original insulating phase. Sood et al. show that a similar sequence occurs when the material is electrically excited with a series of voltage pulses. Using ultrafast electron diffraction, the researchers monitored the structure of a vanadium dioxide sample after excitation and found evidence of a metastable metallic phase that appears during the transition.

Abstract

Superconductivity Thin films of the neodymium nickelate NdNiO2 doped with strontium have recently been found to be superconducting. This materials class bears structural and electronic similarities to the famed cuprate superconductors, but how far the analogy goes remains unclear. Lu et al. used resonant inelastic x-ray scattering to look for magnetism, which exists in the cuprates, in Nd1-xSrxNiO2 films (see the Perspective by Benckiser). The authors observed magnetic modes in the undoped compound that had a doping evolution consistent with the behavior of a doped Mott insulator. Science , abd7726, this issue p.

Abstract

Magnetism Recently discovered two-dimensional (2D) van der Waals magnets exhibit a number of appealing properties, such as a large magnetoresistance. Most of these materials, however, need to be cooled to below room temperature to exhibit these properties and are sensitive to environmental conditions. To address these issues, Chen et al. exploited an old idea, doping an oxide with magnetic atoms, but this time in 2D rather than 3D. The researchers used graphitic zinc oxide, a layered compound in which zinc and oxygen atoms are arranged in a hexagonal pattern, and substituted some zinc atoms with cobalt. The samples exhibited ferromagnetism down to monolayer thickness, even at room temperature. Extrinsic mechanisms for magnetism were excluded with careful characterization and control experiments.

Abstract

Mesoscopic Physics Most experimental claims of Majorana bound states, unusual quasiparticles that may become the cornerstone of topological quantum computing, rest on the observation of a persistent zero bias peak (ZBP) in tunneling spectra. In semiconductor–superconductor heterostructures, this feature may also be caused by the topologically trivial Andreev bound states. Valentini et al. provide comprehensive evidence that the ZBPs observed in their experiments with semiconductor nanowires fully coated with a superconducting shell are indeed of this topologically trivial origin, in contrast to the interpretation of similar earlier experiments. The researchers identify the length of the tunnel junction in their devices as a crucial experimental parameter. Science , abf1513, this issue p. [82][1] [1]: /lookup/doi/10.1126/science.abf1513

Abstract

Superconductivity Among the most intriguing of the many phases of cuprate superconductors is the so-called pair density wave (PDW) state. PDW is characterized by a spatially modulated density of Cooper pairs and can be detected with a scanning tunneling microscope equipped with a superconducting tip. Liu et al. used Josephson tunneling microscopy, modified for the task, to detect PDW in niobium diselenide, a superconductor with a layered hexagonal structure. The PDW state is expected to appear in other transition metal dichalcogenides as well. Science , abd4607, this issue p. [1447][1] [1]: /lookup/doi/10.1126/science.abd4607

Abstract

Ferroelectrics Properties of layered van der Waals structures can depend sensitively on the stacking arrangement of constituent layers. This phenomenon has been exploited to engineer superconducting, correlated insulator, and magnetic states. Two groups now show that ferroelectricity can also be engineered through stacking: Parallel-stacked bilayers of hexagonal boron nitride exhibit ferroelectric switching even though the bulk material is not ferroelectric (see the Perspective by Tsymbal). To explore these phenomena, Yasuda et al. used transport measurements, whereas Vizner Stern et al. focused on atomic force microscopy. Science , abd3230 and abe8177, this issue p. [1458][1] and p.

Abstract

Magnetism Ferromagnetism is associated with the breaking of time-reversal symmetry, most frequently by the spin degree of freedom. Although the orbital motion of electrons can also contribute to ferromagnetism, in most materials, it is small relative to the spin contribution. Tschirhart et al. showed that the reverse is true in an unusual magnetic state hosted by twisted bilayer graphene. Their scanning magnetometry measurements were consistent with ferromagnetism of predominantly orbital origin. Science , abd3190, this issue p. [1323][1] [1]: /lookup/doi/10.1126/science.abd3190

Abstract

Quantum Simulation Ultracold atomic gases are very good at simulating electrons in solids but lack one essential party trick: charge. Their neutrality makes it challenging to simulate phenomena such as the quantum Hall effect, which, in the case of charged electrons, is easily induced by an external magnetic field. One way to produce a similar effect in a neutral system is to rotate it, but achieving the equivalent of strong magnetic fields remains difficult. Fletcher et al. rotated a gas of trapped sodium atoms, reaching a state in which the gas could be described by a single lowest Landau-level wave-function. The system is expected to be a testbed for studying the behavior of strongly interacting many-body states. Science , aba7202, this issue p. [1318][1] [1]: /lookup/doi/10.1126/science.aba7202
