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 …

Direct topological insulator transitions in three dimensions are destabilized by nonperturbative effects of disorder
We reconsider the phase diagram of a three-dimensional Z 2 topological insulator in the
presence of short-ranged potential disorder, with the insight that nonperturbative rare states …

Tilted disordered Weyl semimetals
Although Lorentz invariance forbids the presence of a term that tilts the energy-momentum
relation in the Weyl Hamiltonian, a tilted dispersion is not forbidden and, in fact, generic for …

Absence of localization in Weyl semimetals
One of the fundamental facts of condensed matter physics is that sufficient amount of
disorder always turns a Fermi-liquid metal into an Anderson insulator: a compressible but …

Strong disorder in nodal semimetals: Schwinger-Dyson–Ward approach
B Sbierski, C Fräßdorf - Physical Review B, 2019 - APS
