Abstract
We review a recent method we have developed for Fermion quantum Monte Carlo. By using combinatorial arguments to perform resummations over paths, we reformulate the stochastic problem of sampling paths in terms of sampling “graphs”, which are much better behaved with regards sign-cancellation problems encountered in path-integral simulations of Fermions. Detailed mathematical derivations of the new results are presented.
