Title Flat Space Holography via AdS/BCFT
Abstract We study a new class of AdS/BCFT setups, where the world volumes of end-of-the-world branes (EOW branes) are given by flat spaces,to explore flat space holography from an AdS bulk. We show that they provide gravity duals of CFTs in the presence of null boundaries. Our holographic calculations lead to many new predictions on entanglement entropy, correlation functions and partition functions for CFTs with null boundaries. By considering a bulk region between two EOW branes, we present an AdS/BCFT explanation that the flat space gravity is dual to a Carrollian CFT (CCFT), including the swing surface calculation of entanglement entropy.
