Abstract: Recently, it has been argued that flat-space limit (zero cosmological constant limit) of AdS gravity is dual to the Inonu-Wigner contraction of Conformal Field Theory (CFT) at the boundary. In this talk I will provide an example of a holographic dual of an asymptotically flat black hole solution.
The theory I have been exploring is given by taking the flat-space limit of New Massive Gravity (NMG) and the black hole in it. Furthermore, by taking appropriate limit of the Cardy formula in the parent CFT, I will introduce a Cardy-like formula which reproduces the Walds entropy of the 3D asymptotically flat black hole.
