# Physical black holes in semiclassical gravity

@inproceedings{Murk2021PhysicalBH, title={Physical black holes in semiclassical gravity}, author={Sebastian Murk and Daniel R. Terno}, year={2021} }

We derive and critically examine properties of physical black holes (PBHs) that follow from the formation of a regular apparent horizon in finite time of a distant observer. In spherical symmetry, only two distinct classes of solutions to the semiclassical Einstein equations are self-consistent. Both are required to describe PBH formation and violate the null energy condition in the vicinity of the outer horizon. The near-horizon geometry differs considerably from the one that is described by…

Abstract
In the background of a gravitational collapse, we compute the transition amplitudes for the creation of particles for distant observers due to higher-derivative interactions in addition to…
