Weyl and Dirac semimetals in three-dimensional solids

NP Armitage, EJ Mele, A Vishwanath - Reviews of Modern Physics, 2018 - APS
Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

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 …

Four-loop critical exponents for the Gross-Neveu-Yukawa models

N Zerf, LN Mihaila, P Marquard, IF Herbut, MM Scherer - Physical Review D, 2017 - APS
We study the chiral Ising, the chiral XY, and the chiral Heisenberg models at four-loop order
with the perturbative renormalization group in 4-ε dimensions and compute critical …

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 …

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 …

Dirty Weyl semimetals: Stability, phase transition, and quantum criticality

S Bera, JD Sau, B Roy - Physical Review B, 2016 - APS
We study the stability of three-dimensional incompressible Weyl semimetals in the presence
of random quenched charge impurities. Combining numerical analysis and scaling theory …

Disorder-induced topological quantum phase transitions in multigap Euler semimetals

WJ Jankowski, M Noormandipour, A Bouhon… - Physical Review B, 2024 - APS
We study the effect of disorder in systems having a nontrivial Euler class. As these recently
proposed multigap topological phases come about by braiding non-Abelian charged band …

Phase diagrams of disordered Weyl semimetals

H Shapourian, TL Hughes - Physical Review B, 2016 - APS
Weyl semimetals are gapless quasitopological materials with a set of isolated nodal points
forming their Fermi surface. They manifest their quasitopological character in a series of …

Global phase diagram of a dirty Weyl liquid and emergent superuniversality

B Roy, RJ Slager, V Juričić - Physical Review X, 2018 - APS
Pursuing complementary field-theoretic and numerical methods, we here paint the global
phase diagram of a three-dimensional dirty Weyl system. The generalized Harris criterion …

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 …
