Description

The author presents an algorithm for simulating lattice QCD using the Langevin equation. Systematic errors are analyzed and shown to be mainly renormalization effects and under control. Then demonstrates how critical slowing down can be greatly reduced by updating in momentum space. Fermions are introduced into the Langevin equation in a new way, by including a bilinear noise term. This allows the simulation of any number of flavors, even or odd. Analytic arguments are backed by several numerical experiments
