The Horizon Order Parameter
arXiv:hep-th/0403153
Abstract
We construct a diffeormorphism invariant operator that is sensitive to how far we are from the black hole horizon. Its expectation value blows up on the horizon and it is small away from the horizon. Using this operator, we propose a non-standard effective action that, we argue, captures some of the relevant physics of quantum black holes, including the absence of the horizon at the full quantum level. With the help of a toy version of this effective action, we speculate on a possible connection between UV/IR mixing and the cosmological constant problem.
