Adaptive Optimization of Wave Functions for Fermion Lattice Models
arXiv:hep-lat/0105024 · doi:10.1103/PhysRevD.64.077502
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 systematc 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.
