Roberge-Weiss transition and ’t Hooft loops
Roberge-Weiss transition and ’t Hooft loops
Roberge and Weiss showed that for $SU(N)$ gauge theories, phase transitions occur in the presence of an imaginary quark chemical potential. We show that at asymptotically high temperature, where the phase transition is of first order, that even with dynamical quarks 't Hooft loops of arbitrary $Z(N)$ charge are well …
