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

Minimal models for topological Weyl semimetals
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 …

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 …
