Rare regions and avoided quantum criticality in disordered Weyl semimetals and superconductors

JH Pixley, JH Wilson - Annals of Physics, 2021 - Elsevier
Disorder in Weyl semimetals and superconductors is surprisingly subtle, attracting attention
and competing theories in recent years. In this brief review, we discuss the current …

High-dimensional disorder-driven phenomena in Weyl semimetals, semiconductors, and related systems

SV Syzranov, L Radzihovsky - Annual Review of Condensed …, 2018 - annualreviews.org
It is commonly believed that a noninteracting disordered electronic system can undergo only
the Anderson metal-insulator transition. It has been suggested, however, that a broad class …

Thermoelectric properties of Weyl and Dirac semimetals

R Lundgren, P Laurell, GA Fiete - Physical Review B, 2014 - APS
We study the electronic contribution to the thermal conductivity and the thermopower of Weyl
and Dirac semimetals using a semiclassical Boltzmann approach. We investigate the effect …

Negative longitudinal magnetoresistance in Dirac and Weyl metals

AA Burkov - Physical Review B, 2015 - APS
It has recently been found that Dirac and Weyl metals are characterized by an unusual weak-
field longitudinal magnetoresistance: large, negative, and quadratic in the magnetic field …

Room-temperature valley transistors for low-power neuromorphic computing

Valley pseudospin is an electronic degree of freedom that promises highly efficient
information processing applications. However, valley-polarized excitons usually have short …

Disorder and metal-insulator transitions in Weyl semimetals

CZ Chen, J Song, H Jiang, Q Sun, Z Wang, XC Xie - Physical Review Letters, 2015 - APS
The Weyl semimetal (WSM) is a newly proposed quantum state of matter. It has Weyl nodes
in bulk excitations and Fermi arc surface states. We study the effects of disorder and …

Quantum transport in Dirac materials: Signatures of tilted and anisotropic Dirac and Weyl cones

M Trescher, B Sbierski, PW Brouwer, EJ Bergholtz - Physical Review B, 2015 - APS
We calculate conductance and noise for quantum transport at the nodal point for arbitrarily
tilted and anisotropic Dirac or Weyl cones. Tilted and anisotropic dispersions are generic in …

Rare-region-induced avoided quantum criticality in disordered three-dimensional Dirac and Weyl semimetals

JH Pixley, DA Huse, S Das Sarma - Physical Review X, 2016 - APS
We numerically study the effect of short-ranged potential disorder on massless
noninteracting three-dimensional Dirac and Weyl fermions, with a focus on the question of …

Intrinsic Mechanism for Anisotropic Magnetoresistance and Experimental Confirmation in Single-Crystal Films

FL Zeng, ZY Ren, Y Li, JY Zeng, MW Jia, J Miao… - Physical review …, 2020 - APS
Using first-principles transport calculations, we predict that the anisotropic
magnetoresistance (AMR) of single-crystal Co x Fe 1-x alloys is strongly dependent on the …

Anderson localization and the quantum phase diagram of three dimensional disordered Dirac semimetals

JH Pixley, P Goswami, S Das Sarma - Physical review letters, 2015 - APS
We study the quantum phase diagram of a three dimensional noninteracting Dirac
semimetal in the presence of either quenched axial or scalar potential disorder, by …
