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…

Nematic insulator at charge neutrality in twisted bilayer graphene
Eric Brillaux, David Carpentier, Andrei A. Fedorenko +1
We investigate twisted bilayer graphene near charge neutrality using a generalized Bistritzer-MacDonald continuum model, accounting for corrugation effects. The Fermi velocity vani…
