Description

The Worldvolume Hybrid Monte Carlo (WV-HMC) method is designed to address the numerical sign problem while avoiding the ergodicity issues inherent in the Lefschetz thimble method. Using a general prescription for applying WV-HMC to group manifolds, I demonstrate its successful application to lattice gauge theories with complex actions.
