Superselection sectors of gravitational subregions
Abstract Motivated by the problem of defining the entanglement entropy of the graviton, we study the division of the phase space of general relativity across subregions. Our key requirement is demanding that the separation into subregions is imaginary — i.e., that entangling surfaces are not physica...
