Quenched coupling, entangled equilibria, and correlated composite operators: a tale of two O(N) models
Abstract A macroscopic version of Einstein-Podolsky-Rosen entanglement is obtained by quenching a quadratic coupling between two O(N) vector models.A quench of the mixed vacuum REG TAMPONS W/APP produces an excited entangled state, reminiscent of purified thermal equilibrium, whose properties can be studied analytically in the free limit of the ind
