Real-time lattice gauge theory actions: unitarity, convergence, and path integral contour deformations

no code implementations3 Mar 2021 Gurtej Kanwar, Michael L. Wagman

The character expansion defining the HFK action is divergent, and in this work we apply a path integral contour deformation to obtain a convergent representation for U(1) HFK path integrals suitable for numerical Monte Carlo calculations.

Path integral contour deformations for observables in $SU(N)$ gauge theory

no code implementations29 Jan 2021 William Detmold, Gurtej Kanwar, Henry Lamm, Michael L. Wagman, Neill C. Warrington

We define a family of contour deformations applicable to $SU(N)$ lattice gauge theory that can reduce sign and signal-to-noise problems associated with complex actions and complex observables.
