Description
In this talk we study the impact of altering the standard Hybrid Monte Carlo in numerous small subvolumes of a larger lattice. A primary alteration considered is to fix each subvolume to a maximal tree gauge, such as axial gauge, and then choose conjugate momenta that are not site-local in the subvolume, but rather have spatial coherence acress the subvolume. We focus on pure SU(3) gauge theory and explore whether the choice of non-local conjugate momenta can lead to faster phase-space evolution within the subvolumes and the lattice as a whole.
