Coherent states for black holes

Arundhati Dasgupta

Show affiliations


We determine coherent states peaked at the classical spacetime of the Schwarzschild black hole in the framework of canonical quantization of general relativity. The information about the horizon is naturally encoded in the phase space variables, and the perturbative quantum fluctuations around the classical geometry depend on the distance from the horizon. For small black holes, space near the vicinity of the singularity appears discrete with the singular point excluded from the spectrum.
