Ab initio study of metallic aluminum hydrides at high pressures

By Kazutaka Abe from Recent Articles in Phys. Rev. B. Published on Nov 13, 2019.

Author(s): Kazutaka Abe

Metallic phases of ${\mathrm{Al}}_{2}\mathrm{H}$ and AlH at megabar pressures are predicted to be possible by using ab initio density functional calculations. The ${\mathrm{Al}}_{2}\mathrm{H}$ phase is stabilized above 155 GPa, where several candidate structures are quite competitive; the structural...

Threshold interface magnetization required to induce magnetic proximity effect

By O. Inyang, L. Bouchenoire, B. Nicholson, M. Tokaç, R. M. Rowan-Robinson, C. J. Kinane, and A. T. Hindmarch from Recent Articles in Phys. Rev. B. Published on Nov 13, 2019.

Author(s): O. Inyang, L. Bouchenoire, B. Nicholson, M. Tokaç, R. M. Rowan-Robinson, C. J. Kinane, and A. T. Hindmarch

Magnetism can be induced in nominally nonmagnetic metals, such as platinum, as a result of proximity to an adjacent ferromagnet. This proximity-induced magnetism is typically weak and decays over a length scale on the order of nanometers, making the elucidation of the underlying physics experimentally challenging. The authors use a combination of polarized neutron reflectivity to probe depth-resolved magnetization in the ferromagnet and x-ray resonant magnetic reflectivity to provide an element-specific probe of depth-resolved magnetism in platinum. This allows for a direct comparison of the proximity-induced magnetism in platinum with the magnetization close to the interface within the ferromagnet.

Sampling scheme for neuromorphic simulation of entangled quantum systems

By Stefanie Czischek, Jan M. Pawlowski, Thomas Gasenzer, and Martin Gärttner from Recent Articles in Phys. Rev. B. Published on Nov 13, 2019.

Author(s): Stefanie Czischek, Jan M. Pawlowski, Thomas Gasenzer, and Martin Gärttner

Neural networks can be used to represent a large class of quantum many-body states in a classical-statistical manner. This includes entangled states such as the paradigmatic Bell states or a quantum Ising chain near its critical point. The task of sampling from these states may be performed efficiently by physically implementing the network on neuromorphic hardware. A deep neural network structure is proposed for the sampling of arbitrary and, in general, noncommuting observables, where a phase-reweighting scheme is used in view of the complex coupling parameters. Entanglement is demonstrated through the violation of Bell inequalities.

Weyl semimetals exhibit anomalous electronic transport due to the presence of topological band crossings, called Weyl nodes. In this work, experimental and theoretical results show that EuCd2As2 in a magnetic field is what Bernevig has termed the hydrogen atom of a Weyl semimetal, i.e. one with a single pair of Weyl nodes at the Fermi level and without overlapping electron bands. The discovery opens the door to a wide range of exotic physics, predicted for Weyl fermions in the solid state.

Symmetry and quantum kinetics of the nonlinear Hall effect

By S. Nandy and Inti Sodemann from Recent Articles in Phys. Rev. B. Published on Nov 12, 2019.

Author(s): S. Nandy and Inti Sodemann

Unlike the ordinary Hall effect, the nonlinear Hall effect (NLHE) can occur in time-reversal-invariant metals lacking inversion symmetry. The authors uncover that two disorder-mediated corrections to the NLHE, namely, the nonlinear side jump and the nonlinear skew scattering, can be as large as the intrinsic Berry curvature dipole contribution. These findings will help to understand recent experiments searching for NLHE in various materials. They also offer a description of the role of disorder in current rectification in materials without inversion symmetry that could be relevant for wireless energy harvesting technology.

Two mechanisms of Josephson phase shift generation by an Abrikosov vortex

Author(s): T. Golod, A. Pagliero, and V. M. Krasnov

Abrikosov vortices contain magnetic fields and circulating currents that decay at a short range $λ∼100$ nm. However, vortices can induce Josephson phase shifts at a long range $r∼μ\mathrm{m}≫λ$. Mechanisms of this puzzling phenomenon are not clearly understood. Here we present a systematic study of ...

Author(s): S. K. Gotovko, L. E. Svistov, A. M. Kuzmenko, A. Pimenov, and M. E. Zhitomirsky

Spin structures realized in magnetic materials with competing exchange interactions depend crucially on weak additional interactions, such as relativistic magnetic anisotropies, farther-neighbor exchanges, etc. This is the case in the natural magnetic mineral linarite, which has attracted a lot of attention due to its rich phase diagram. Electron spin resonance (ESR) is a sensitive experimental technique that allows to probe the presence and magnitude of magnetic anisotropies. The authors have measured the ESR modes in linarite over a broad frequency range and for various field geometries. The accompanying theoretical analysis provides accurate estimates for the magnetic anisotropy constants that, in turn, influence the presence of exotic multipolar states.

Author(s): Stefan G. Fischer, Jinhong Park, Yigal Meir, and Yuval Gefen

A theoretical analysis reveals the physical origin behind energetic signatures, measured in an electron spectrometer, that have recently been realized experimentally. In the device, electrons are injected and detected at specific energies. Surprisingly, signals arise in which the detection energy exceeds the injection energy. The theoretical treatment shows that these signals can be linked to interactions that were so far thought to be negligible in the description of mesoscopic samples, between electrons that propagate in spatially separate parts of the spectrometer.

Electron phonon coupling (EPC) between surface electronic states and surface phonons is significant for low-dimensional devices. This is especially important for topological materials with exotic surface states. The authors experimentally map out the surface phonon dispersions of a topological nodal line semimetal ZrSiS with exotic surface floating two-dimensional electronic bands. They reveal a prominent Kohn anomaly in a surface phonon branch, originating from the interactions with the two-dimensional electrons. This discovery provides an EPC picture, important for the applications of topological nodal line semimetals.

Author(s): Álvaro M. Alhambra, Georgios Styliaris, Nayeli A. Rodríguez-Briones, Jamie Sikora, and Eduardo Martín-Martínez

We examine when it is possible to locally extract energy from a bipartite quantum system in the presence of strong coupling and entanglement, a task which is expected to be restricted by entanglement in the low-energy eigenstates. We fully characterize this distinct notion of “passivity” by finding ...
