High Energy Theory Seminar

In AdS/CFT, geometrical and causal features of entanglement wedges (certain subsystems of the gravitational theory) reflect the algebraic structure of the underlying quantum theory (the CFT). Recently, Bousso and Penington have suggested a definition of entanglement wedges in general spacetimes. In this talk, we explore the hypothesis that as for ordinary entanglement wedges, each such wedge may be associated with a subalgebra in the (generally unknown) underlying fundamental description. Assuming this is true, we postulate features of the map between entanglement wedges and algebras that would allow the geometrical properties of generalized entanglement wedges proved by Bousso and Penington to be recovered from the properties of the associated algebras. The goal is to gain insight into the possible mathematical structure of quantum gravity beyond AdS/CFT.

The talk is in 469 Lauritsen.
