Abstract

Based on the tight-binding model we construct a nonlinear Hamiltonian to describe the effective electric system around the M point for the single layer graphene. The local energy spectrum at the M point is approximated by the perfect hyperbolic geometry, and the modification by the screening effect from the substrate is taken into account.
