Abstract

Complex Langevin methods have been successfully applied in theories that suffer
from a sign problem such as QCD with a chemical potential. We present and
illustrate a novel method (dynamic stabilisation) that ensures that Complex
Langevin simulations stay close to the SU(3) manifold, which lead to correct and improved results in the framework of pure Yang-Mills simulations and QCD in the limit of heavy
quarks.
