Complex Langevin: Boundary terms and application to QCD
Abstract
We employ the Complex Langevin method for simulation of complex-valued actions. First, we show how to test for convergence of the method by explicitely computing boundary terms and demonstrate this in a model. Then we investigate the deconfinement phase transition of QCD with Nf=2 Wilson-fermions using the Complex Langevin Method and. We give preliminary results for the transition temperatures up to μ/Tc(μ=0)≈ 5 and compute the curvature coefficient 2.
