Abstract

The influence of Barry’s phase on the particle motion in graphene is analyzed by means of a quantum phase-space approach. Our procedure is based on a reformulation of the Wigner formalism where the multiband particle-hole dynamics is described in terms of the Berry curvature. The emergence of some adiabatic parameters for the description of the quasi-classical trajectories in the presence of an external electric field is also discussed.
