A time dependent ER=EPR for closed FRW cosmologies

Abstract: In this talk, I will discuss extensions of the static patch holographic proposal for de Sitter space and entanglement entropy calculation prescriptions to generic closed FRW cosmologies in arbitrary dimensions. For large classes of bouncing and Big Bang/Big Crunch cosmologies, the spacetime can be encoded on two holographic screens at the apparent horizons associated to observers at antipodal points of the spatial sphere. The leading contributions to the entanglement entropy between the screens arise from a minimal extremal trapped or anti-trapped sphere in the region between the apparent horizons. The picture amounts to a time-dependent, cosmological realization of the ER=EPR conjecture. For the Big Crunch contracting cases, the screens disentangle with the geometrical bridge between them closing off when the minimal extremal trapped sphere hits the Big Crunch singularity at a time before the collapse of the Universe.
