Dispersion relation of Landau elementary excitations and thermodynamic properties of superfluid He4

H. Godfrin, K. Beauvois, A. Sultan, E. Krotscheck, J. Dawidowski, B. Fåk, and J. Ollivier

Phys. Rev. B 103, 104516 (2021) - Published 29 March, 2021

Superfluid 4He, a strongly correlated Bose-Einstein condensed many-body system, displays sharp phonon-roton quantized excitations. Here, the authors report a complete determination of the dispersion relation of these excitations, using the most advanced inelastic neutron scattering methods as well as detailed dynamic many-body theory calculations. From the measured dispersion, the authors obtain, analytically as well as numerically, accurate tables of the thermodynamic properties. These highly precise results provide indispensable reference for a large variety of fundamental experimental and theoretical studies.

Time-dependent self-consistent harmonic approximation: Anharmonic nuclear quantum dynamics and time correlation functions

Lorenzo Monacelli and Francesco Mauri

Phys. Rev. B 103, 104305 (2021) - Published 23 March, 2021

Simulating nuclear quantum dynamics in strongly anharmonic materials is an open challenge where state-of-the-art techniques fail. This is relevant in ferroelectrics, charge density waves, and crystals encapsulating light atoms, such as superconductive high-pressure hydrides. Here, the authors develop a theory to compute dynamical properties and predict experimental Raman and IR spectroscopy, neutron scattering, and x-ray scattering of any material, accounting for the nuclear quantum and anharmonic dynamics.The method is efficient and can be applied to systems with hundreds of atoms even when treating electrons ab initio within density functional theory.

Statistical mechanics of quantum error correcting codes

Yaodong Li and Matthew P. A. Fisher

Phys. Rev. B 103, 104306 (2021) - Published 24 March, 2021

Random quantum dynamics generates quantum error correcting codes that are robust against observers and errors. Here, the authors describe a simple physical picture of such codes, mapping characteristic code properties to the statistical mechanics of fluctuating “entanglement domain walls”. The error correcting criterion is understood as a decoupling condition of domain walls, which leads to a universal scaling law of the “code distance”.

Néel-type skyrmions and their current-induced motion in van der Waals ferromagnet-based heterostructures

Tae-Eon Park et al.

Phys. Rev. B 103, 104410 (2021) - Published 5 March, 2021

There have been extensive efforts to engineer magnetic two-dimensional materials with a view to using them for spintronic applications, in conjunction with other materials from the two-dimensional family. Here, the authors reveal Néel-type chiral magnetic skyrmions and their lattice formation in the van der Waals ferromagnet Fe3GeTe2 (FGT). They demonstrate the capability to drive an individual skyrmion by current along this van der Waals heterostructure on h-BN. Utilizing ab initio calculations, the study proposes the presence of Dzyaloshinskii-Moriya interaction at FGT interfaces with oxidized layers.

Topological anomalous skin effect in Weyl superconductors

Tsz Chun Wu, Hridis K. Pal, and Matthew S. Foster

Phys. Rev. B 103, 104517 (2021) - Published 30 March, 2021

Superconductors absorb light despite having infinite dc conductivity. In a topologically trivial superconductor, such absorption is typically facilitated by disorder, giving rise to the anomalous skin effect. Here, the authors demonstrate that topology can mediate a new mechanism of optical absorption, dubbed the “topological anomalous skin effect”. In clean topological superconductors, the presence of surface states allow surface-to-bulk optical transitions. Specifically, for Weyl superconductors, the authors predict a characteristic absorption peak, which also survives in the presence of weak disorder.

Stark many-body localization: Evidence for Hilbert-space shattering

Elmer V. H. Doggen, Igor V. Gornyi, and Dmitry G. Polyakov

Phys. Rev. B 103, L100202 (2021) - Published 4 March, 2021

The ergodic hypothesis lies at the heart of classical statistical physics. A crucial question, therefore, is how this idea translates into the quantum world. Many-body localization – the analog of Anderson localization to the many-body case – has emerged as a key example of nonergodicity. Here, the authors analyze a disorder-free Heisenberg spin chain under the influence of a constant field gradient (Stark many-body localization). Surprisingly, they find that nonergodicity results, even for a vanishingly small gradient.

Topological and symmetry-enriched random quantum critical points

Carlos M. Duque, Hong-Ye Hu, Yi-Zhuang You, Vedika Khemani, Ruben Verresen, and Romain Vasseur

Phys. Rev. B 103, L100207 (2021) - Published 30 March, 2021

Topological phases represent a pillar of modern condensed matter physics. While gapped topological systems have been studied extensively, gapless topological materials represent an exciting, largely unexplored area. Here, the authors show that symmetry can enrich random quantum critical points and phases. They uncover a class of gapless topological phases, protected by symmetry and robust to strong randomness. Some of these phases can be realized in nonequilibrium states stabilized by many-body localization. They also appear naturally in periodically driven (Floquet) systems.

Intrinsic and extrinsic tunability of Rashba spin-orbit coupled emergent inductors

Jun'ichi Ieda and Yuta Yamane

Phys. Rev. B 103, L100402 (2021) - Published 4 March, 2021

By integrating the spin-orbit coupling, both the amplification mechanism of the quantum version of inductance, and the origin of “negative inductance” that was not possible in a single device, are clarified. The findings will stimulate research in miniaturization of power supply circuits and electromagnetic noise reduction based on negative inductance, which will ultimately determine the size and weight of electronic devices. The achievement here will help open up a new technological field of “power spintronics”, in which power is controlled via spin-based quantum technology.

Direct imaging of electrical switching of antiferromagnetic Néel order in αFe2O3 epitaxial films

Egecan Cogulu, Nahuel N. Statuto, Yang Cheng, Fengyuan Yang, Rajesh V. Chopdekar, Hendrik Ohldag, and Andrew D. Kent

Phys. Rev. B 103, L100405 (2021) - Published 10 March, 2021

X rays have been used to image the spin directions in an antiferromagnetic thin film of hematite (α-Fe2O3) and show how they reorient in response to electrical pulses. Spin switching is shown to depend on the current direction and occurs even outside the current path. The results here show that, in addition to any direct interaction between the electrical current and the spins, thermal effects lead to spin reorientation, highlighting the delicate balance of interactions important to understanding the physics of current-induced switching in antiferromagnets.

Superfluid 4He, a strongly correlated Bose-Einstein condensed many-body system, displays sharp phonon-roton quantized excitations. Here, the authors report a complete determination of the dispersion relation of these excitations, using the most advanced inelastic neutron scattering methods as well as detailed dynamic many-body theory calculations. From the measured dispersion, the authors obtain, analytically as well as numerically, accurate tables of the thermodynamic properties. These highly precise results provide indispensable reference for a large variety of fundamental experimental and theoretical studies.

Topological anomalous skin effect in Weyl superconductors

Tsz Chun Wu, Hridis K. Pal, and Matthew S. Foster

Phys. Rev. B 103, 104517 (2021) - Published 30 March, 2021

Superconductors absorb light despite having infinite dc conductivity. In a topologically trivial superconductor, such absorption is typically facilitated by disorder, giving rise to the anomalous skin effect. Here, the authors demonstrate that topology can mediate a new mechanism of optical absorption, dubbed the “topological anomalous skin effect”. In clean topological superconductors, the presence of surface states allow surface-to-bulk optical transitions. Specifically, for Weyl superconductors, the authors predict a characteristic absorption peak, which also survives in the presence of weak disorder.
