Sampling using SU ( N ) gauge equivariant flows

We develop a flow-based sampling algorithm for SU ( N ) lattice gauge theories that is gauge invariant by construction. Our key contribution is constructing a class of flows on an SU ( N ) variable [or on a U ( N ) variable by a simple alternative] that respects matrix conjugation symmetry. We apply...
