Query: Local quenches, bulk entanglement entropy and a unitary Page curve   Quantum corrections to the entanglement entropy of matter fields interacting
with dynamical gravity have proven to be very important in the study of the
black hole information problem. We consider a one-particle excited state of a
massive scalar field infalling in a pure AdS$_3$ geometry and compute these
corrections for bulk subregions anchored on the AdS boundary. In the dual
CFT$_2$, the state is given by the insertion of a local primary operator and
its evolution thereafter. We calculate the area and bulk entanglement entropy
corrections at order $\mathcal{O}(N^0)$, both in AdS and its CFT dual. The two
calculations match, thus providing a non-trivial check of the FLM formula in a
dynamical setting. Further, we observe that the bulk entanglement entropy
follows a Page curve. We explain the precise sense in which our setup can be
interpreted as a simple model of black hole evaporation and comment on the
implications for the information problem.
