BMS Symmetry via AdS/CFT
arXiv:2007.02851 · doi:10.1007/JHEP01(2021)075
Abstract
With a view to understanding extended-BMS symmetries in the framework of the correspondence, asymptotically AdS geometries are constructed with null impulsive shockwaves involving a discontinuity in superrotation parameters. The holographic dual is proposed to be a two-dimensional Euclidean defect conformal field localized on a particular timeslice in a three-dimensional conformal field theory on de Sitter spacetime. The defect conformal field theory generates a natural action of the Virasoro algebra. The large radius of curvature limit yields spacetimes with nontrivial extended-BMS charges.
