Numerical study of the two dimensional Heisenberg model by Green Function Monte Carlo at fixed number of walkers

M. Calandra, S. Sorella

We describe in detail a simple and efficient Green Function Monte Carlo technique for computing both the ground state energy and the ground state properties by the ``forward walkin…
