Strong coupling expansion Monte Carlo

Abstract

We give an overview on recently accomplished successful generalizations of `worm' or loop gas simulation methods to O(N) and CP(N-1) sigma models and to simple fermion models. Beside the advantage of (practically) eliminated critical slowing down we also explain additional opportunities to estimate some observables with extremely improved signal to noise levels.
