Numerical solution of the Dirac equation for an armchair graphene nanoribbon in the presence of a transversally variable potential

We compute, using a continuum model based on the Dirac equation, the transverse modes and the longitudinal wave vectors in an armchair ribbon, in the presence of a transversally variable external potential. We show that the application of a standard finite difference method to this problem is not ef...
