Title: Looking for Emergent Locality

Abstract:

Entanglement entropy can provide a powerful diagnostic of locality. However, in our most promising theories of quantum gravity, space emerges from some more fundamental "non-geometric" degrees of freedom. Speaking about local partitions in this emergent space poses a challenge. Starting with the example of single-particle quantum mechanics, we define a novel type of spatial entanglement related to partitions of the target space values of fields. We apply this formalism to a simple toy model of string theory in two dimensions, and find it reproduces the entanglement entropy of the tachyon field in an emergent 2d spacetime. We comment on potential broader applications to holography.
