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 analytically in the free limit of the individual field theories. https://fitnessgravesyardes.shop/product-category/step-platform/
