Black Hole Entropy in Induced Gravity: Reduction to 2D Quantum Field Theory on the Horizon
arXiv:hep-th/9806078 · doi:10.1103/PhysRevD.58.124009
Abstract
It is argued that degrees of freedom responsible for the Bekenstein-Hawking entropy of a black hole in induced gravity are described by two dimensional quantum field theory defined on the bifurcation surface of the horizon. This result is proved for a class of induced gravity models with scalar, spinor and vector heavy constituents.
