Berry phase and pseudospin winding number in bilayer graphene
Ever since the novel quantum Hall effect in bilayer graphene was discovered, and explained by a Berry phase of 2π [ K. S. Novoselov et al. Nat. Phys. 2 177 (2006)], it has been widely accepted that the low-energy electronic wave function in this system is described by a nontrivial Berry phase of 2π,...
