Surface quantum critical phenomena in disordered Dirac semimetals
Eric Brillaux, Andrei A. Fedorenko, Ilya A. Gruzberg
We study a non-Anderson disorder driven quantum phase transition in a semi-infinite Dirac semimetal with a flat boundary. The conformally invariant boundary conditions, which inclu…

Fermi arcs and surface criticality in dirty Dirac materials
Eric Brillaux, Andrei A. Fedorenko
We study the effects of disorder on semi-infinite Weyl and Dirac semimetals where the presence of a boundary leads to the formation of either Fermi arcs/rays or Dirac surface state…

Multifractality at the Weyl semimetal-diffusive metal transition for generic disorder
Eric Brillaux, David Carpentier, Andrei A. Fedorenko
A Weyl semimetal is a three dimensional topological gapless phase. In the presence of strong enough disorder it undergoes a quantum transition towards a diffusive metal phase whose…
