Abstract

A self-consistent microscopic theory is applied to analyze the influence of many-body effects on the energy spectrum of biased bilayer graphene. The results show a monotonic increase of the quasiparticle gap with the applied external field and a significant enhancement of the gap due to the many-body interactions.
