Quantum back reaction on the black hole space-time negative cosmological constant |
|
Abstract |
We investigate quantum back reactions of CFT fields on black hole (BH) space-time with negative cosmological constant by using radiation fluid approximation in which we describe quantum fields as radiation fluids. We analyze the thermodynamical quantity of the system and find that when the BH horizon radius is bigger than space-time curvature scale, the system is thermodynamically stable but when BH radius is smaller than curvature scale, the system is unstable. In the context of AdS/CFT correspondence on the brane world model, this may mean large BHs can be localized on the brane with the stable shapes and small BH can be localized only with the unstable shapes in Karch Randall model. |
