Quotient-AdS/BCFT: Holographic Boundary CFT2 on AdS3 Quotients
Abstract
The holographic principle, being a generic feature of quantum gravity, should allow for the consideration of dualities other than AdS/CFT. The AdS/BCFT correspondence, in which the dual field theory has local conformal symmetry and is defined on a manifold with boundary, is one such example. Inspired by the quotienting of AdS3 by spacetime isometries in order to construct multiboundary wormholes dual to multipartite CFT2 states, we find that this correspondence can be understood by combining AdS/CFT with some appropriate quotient procedure. Furthermore, in three bulk dimensions, we find example quotient spaces of AdS3 in order to construct "natural" bulk duals for specific BCFT2 vacuum states, one of which appears to describe a novel, time-dependent BCFT2 solution. We call this particular refinement of AdS/BCFT, in which we use quotients, the quotient-AdS/BCFT correspondence.
