DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CCTP_HEP/7/"
 >The holographic CFT masquerade</a>\nby Mark Van Raamsdonk (University of 
 British Columbia) as part of CCTP HEP Seminars\n\n\nAbstract\nWe argue tha
 t given holographic CFT1 in some state with a dual spacetime geometry M\, 
 and given some other holographic CFT2\, we can find states of CFT2 whose d
 ual geometries closely approximate arbitrarily large causal patches of M\,
  provided that CFT1 and CFT2 can be non-trivially coupled at an interface.
  Our CFT2 states are ``dressed up as'' states of CFT1: they are obtained f
 rom the original CFT1 state by a regularized quench operator defined using
  a Euclidean path-integral with an interface between CFT2 and CFT1. Our re
 sults are consistent with the idea that the precise microscopic degrees of
  freedom and Hamiltonian of a holographic CFT are only important in fixing
  the asymptotic behavior of a dual spacetime\, while the interior spacetim
 e of a region spacelike separated from a boundary time slice is determined
  by more universal properties (such as entanglement structure) of the quan
 tum state at this time slice. Our picture requires that low-energy gravita
 tional theories related to CFTs that can be non-trivially coupled at an in
 terface are part of the same non-perturbative theory of quantum gravity.\n
