The Factorization Method for Simulating Systems with a Complex Action
Abstract
We propose a method for Monte Carlo simulations of systems with a complex action. The method has the advantages of being in principle applicable to any such system and provides a solution to the overlap problem. We apply it in random matrix theory of finite density QCD where we compare with analytic results. In this model we find non-commutativity of the limits μ → 0 and N → ∞ which could be of relevance in QCD at finite density.
