Revealing the non-adiabatic and non-Abelian multiple-band effects via anisotropic valley Hall conduction in bilayer graphene
Many quantum materials of interest, eg bilayer graphene, possess a number of closely
spaced but not fully degenerate bands near the Fermi level, where the coupling to the far …
