Title: Universal conductivity and dimensional crossover in multi-layer graphene
 
Abstract: We show, by exact Renormalization Group methods, that in multi-layer graphene the dimensional crossover energy scale is decreased by the intra-layer interaction, and that for temperatures and frequencies greater than such scale the conductivity is close to the one of a stack of independent layers up to small corrections.

Keywords: bilayer graphene, transverse conductivity, confinement, Ward identities, renormalization group,
