The abundance of such s ystems raises the question of whether this is a universal feature of all q uantum systems. In this talk\, I will present examples of (3+1)-dimensiona l non-supersymmetric large N gauge theories which demonstrate violations o f the above feature. I will argue that in the N tending to infinity limit\ , these theories have conformal manifolds which survive under all loop cor rections to the beta functions of the couplings. I will show that under ce rtain conditions\, a subset of points on such a conformal manifold demonst rates the spontaneous breaking of a global symmetry at all nonzero tempera tures. Furthermore\, I will demonstrate that this symmetry breaking is acc ompanied by the Higgsing of a subset of gauge bosons leading the system to be in a persistent Brout-Englert-Higgs phase\n LOCATION:https://researchseminars.org/talk/PUHET/20/ END:VEVENT END:VCALENDAR
