✦ Synopsis

A new method is presented for the exact stochastic solution of the ground states of many-Fermion systems. The antisymmetric ground state wavefunction is expressed as the difference between two positive functions, and the non-linear coupled Schriidinger equation for these functions is solved by a generalized path integral Monte Carlo technique. The method is tested on a two-dimensional example, and its applicability to realistic problems is discussed.
