Charged skyrmions and topological origin of superconductivity in magic-angle graphene

E Khalaf, S Chatterjee, N Bultinck, MP Zaletel… - Science …, 2021 - science.org
Topological solitons, a class of stable nonlinear excitations, appear in diverse domains as in
the Skyrme model of nuclear forces. Here, we argue that similar excitations play an …

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 …

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 …

Minimal models for topological Weyl semimetals

TM McCormick, I Kimchi, N Trivedi - Physical Review B, 2017 - APS
Topological Weyl semimetals (TWS) can be classified as type I TWS, in which the density of
states vanishes at the Weyl nodes, and type II TWS, in which an electron pocket and a hole …

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 …

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 …

Topological diffusive metal in amorphous transition metal monosilicides

S Franca, AG Grushin - Physical Review Materials, 2024 - APS
In chiral crystals crystalline symmetries can protect multifold fermions, pseudorelativistic
masless quasiparticles that have no high-energy counterparts. Their realization in transition …
