摘要

We describe and discuss a recently proposed quantum Monte Carlo algorithm to compute the ground-state properties of various systems of interacting fermions. In this method, the ground state is projected fi om an initial wave function by a branching random walk in an overcomplete basis of Slater determinants. By constraining the determinan...更多
