Partial deconfinement at strong coupling on the lattice

Zusammenfassung

We provide evidence for partial deconfinement - the deconfinement of a SU(M) subgroup of the SU(N) gauge group - by using lattice Monte Carlo simulations. We take matrix models as concrete examples. By appropriately fixing the gauge, we observe that the M x M submatrices deconfine. This gives direct evidence for partial deconfinement at strong coupling. We discuss the applications to QCD and holography.
