Magnetic and noncentrosymmetric Weyl fermion semimetals in the family of compounds ()
Weyl semimetals are novel topological conductors that host Weyl fermions as emergent
quasiparticles. In this Rapid Communication, we propose a new type of Weyl semimetal …

Parton construction of a wave function in the anti-Pfaffian phase
In this work we propose a parton state as a candidate state to describe the fractional

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 …
