Symmetry and quantum kinetics of the nonlinear Hall effect

S. Nandy and Inti Sodemann

Phys. Rev. B 100, 195117 (2019) - Published 12 November, 2019

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.

Sampling scheme for neuromorphic simulation of entangled quantum systems

Stefanie Czischek, Jan M. Pawlowski, Thomas Gasenzer, and Martin Gärttner

Phys. Rev. B 100, 195120 (2019) - Published 13 November, 2019

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.

Learnability scaling of quantum states: Restricted Boltzmann machines

Dan Sehayek, Anna Golubeva, Michael S. Albergo, Bohdan Kulchytskyy, Giacomo Torlai, and Roger G. Melko

Phys. Rev. B 100, 195125 (2019) - Published 15 November, 2019

Motivated by the recent success of machine learning techniques in many-body physics, the authors study the scaling complexities of quantum state reconstruction in the restricted Boltzmann machine on the paradigmatic one-dimensional transverse-field Ising model. The authors demonstrate that the scaling complexities in the number of parameters and in the size of the training data are polynomial. Moreover, they show that the number of parameters required for reconstruction can be significantly reduced via pruning out network weights – indicating that overparameterization is required to facilitate the learning process.

Coupled structural distortions, domains, and control of phase competition in polar SmBaMn2O6

Elizabeth A. Nowadnick, Jiangang He, and Craig J. Fennie

Phys. Rev. B 100, 195129 (2019) - Published 18 November, 2019

Understanding and controlling the competing ground states realized in correlated oxides is a significant challenge. Manipulating subtle geometric distortions to crystal structure provides an opportunity to control these states by changing the environment in which electrons interact. Here, the authors explore the structurally complex polar manganite SmBaMn2O6 and reveal how a set of coupled structural distortions stabilize the ground state. They show how modulations to crystal structure at domain walls and in epitaxially strained thin films can stabilize competing phases.

Wilson loop approach to fragile topology of split elementary band representations and topological crystalline insulators with time-reversal symmetry

Adrien Bouhon, Annica M. Black-Schaffer, and Robert-Jan Slager

Phys. Rev. B 100, 195135 (2019) - Published 21 November, 2019

Recently, there has been rapid progress in classifying topological band structures by examining possible configurations, arising through consideration of the constraints of the underlying lattice symmetry. Apart from topologically stable and trivial bands, these pursuits have identified fragile topologies that can be trivialized by additional bands. The authors present a general and directly implementable tool to diagnose the full topological characterization of bands using Wilson flows. As a result, they find a general relation and unambiguous representation of these novel topological concepts.

Fracton fusion and statistics

Shriya Pai and Michael Hermele

Phys. Rev. B 100, 195136 (2019) - Published 22 November, 2019

Universal properties of quasiparticle excitations, such as fusion and statistics of anyons in two dimensions, play a central role in characterizing quantum phases of matter. Here, the authors develop a systematic framework to describe fusion and statistical processes of fractons and other quasiparticle excitations with subdimensional mobility. The restricted mobility of excitations leads to statistical processes that differ dramatically from more familiar braiding processes of anyons.

Electron-phonon coupling and Kohn anomaly due to floating two-dimensional electronic bands on the surface of ZrSiS

Siwei Xue, Tiantian Zhang, Changjiang Yi, Shuyuan Zhang, Xun Jia, Luiz H. Santos, Chen Fang, Youguo Shi, Xuetao Zhu, and Jiandong Guo

Phys. Rev. B 100, 195409 (2019) - Published 7 November, 2019

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.

Interaction-induced charge transfer in a mesoscopic electron spectrometer

Stefan G. Fischer, Jinhong Park, Yigal Meir, and Yuval Gefen

Phys. Rev. B 100, 195411 (2019) - Published 8 November, 2019

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.

Bridging between laboratory and rotating-frame master equations for open quantum systems

Gal Shavit, Baruch Horovitz, and Moshe Goldstein

Phys. Rev. B 100, 195436 (2019) - Published 27 November, 2019

The evolution of a driven open quantum system is often described by the Lindblad master equation. Two prevalent forms of this equation involve approximations with distinct and limited applicability ranges, possibly leading to different outcomes. This work introduces a generalized approach bridging between the two previous methods and uncovering novel behavior in previously inaccessible regimes. The relevance of the generalized approach to quantum-technology systems, such as cavity-coupled quantum dots and single-spin EPR experiments, is demonstrated.

The evolution of a driven open quantum system is often described by the Lindblad master equation. Two prevalent forms of this equation involve approximations with distinct and limited applicability ranges, possibly leading to different outcomes. This work introduces a generalized approach bridging between the two previous methods and uncovering novel behavior in previously inaccessible regimes. The relevance of the generalized approach to quantum-technology systems, such as cavity-coupled quantum dots and single-spin EPR experiments, is demonstrated.
