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 produces an excited entangled state, reminiscent of purified thermal equilibrium, whose properties can be studied analytic...
