Abstract

By combining diffusion Monte Carlo for the spatial degrees of freedom and auxiliary field Monte Carlo to separate the spin-isospin operators, we can solve for the ground state of many-nucleon systems. We use a path constraint to control the fermion sign problem and apply the method to neutron systems interacting with the Argonne ν′s two nucleon potential and the Urbana IX three-nucleon potential. We compare our results with fermion hypernetted chain calculations.
