Probing center vortices and deconfinement in lattice gauge theory with persistent homology

arXiv:2207.13392 · doi:10.1103/PhysRevD.107.034501

Abstract

We investigate the use of persistent homology, a tool from topological data analysis, as a means to detect and quantitatively describe center vortices in lattice gauge theory in a gauge-invariant manner. We provide evidence for the sensitivity of our method to vortices by detecting a vortex explicitly inserted using twisted boundary conditions in the deconfined phase. This inspires the definition of a new phase indicator for the deconfinement phase transition. We also construct a phase indicator without reference to twisted boundary conditions using a simple -nearest neighbours classifier. Finite-size scaling analyses of both persistence-based indicators yield accurate estimates of the critical and critical exponent of correlation length of the deconfinement phase transition.
