Complex Langevin analysis of 2D U(1) gauge theory on a torus with a θ term

Abstract Monte Carlo simulation of gauge theories with a θ term is known to be extremely difficult due to the sign problem. Recently there has been major progress in solving this problem based on the idea of complexifying dynamical variables. Here we consider the complex Langevin method (CLM), which...
