Abstract

We present a simulation algorithm for Hamiltonian fermion lattice models. A guiding trial wave function is adaptively optimized during Monte Carlo evolution. We apply the method to the two dimensional Gross-Neveu model and analyze systematic errors in the study of ground state properties. We show that accurate measurements can be achieved by a proper extrapolation in the algorithm-free parameters.
