I will briefly review the Hamiltonian of the graphene system and show how the partition function and Green's functions for the quadratic Hamiltonian can be expressed in path integral form by using fermion coherent states. I will then show how one can incorporate the Coulomb interaction into the path integral and how this can be simulated with the hybrid Monte Carlo technique. I will present then early results for the Green's functions obtained with this method. (Based on research done in collaboration with Richard Brower and David Schaich.)
