Deconstructing Ünsal-Yaffe reconfinement

In the UY reconfined phase on a lattice the thermal trace is over states transforming in all SU(N)/Z(N) irreducible representations as opposed to only over SU(N) singlets in the standard formulation. As N→∞, on a finite lattice, the usual Hilbert space becomes orthogonal to the deformed one. Concern...

Zusammenfassung:In the UY reconfined phase on a lattice the thermal trace is over states transforming in all SU(N)/Z(N) irreducible representations as opposed to only over SU(N) singlets in the standard formulation. As N→∞, on a finite lattice, the usual Hilbert space becomes orthogonal to the deformed one. Concerns about the extended UY proposal for large N Eguchi-Kawai reduction are raised.
