# The fate of horizons under quantum corrections

@inproceedings{lvarez2022TheFO, title={The fate of horizons under quantum corrections}, author={Enrique {\'A}lvarez and Jes{\'u}s G Anero and Eduardo Velasco-Aja}, year={2022} }

In this paper, we study the physical eﬀects of deforming the usual Einstein-Hilbert lagrangian with the Goroﬀ-Sagnotti counterterm (the ﬁrst which is nonvanishing on shell). Only spherically symmetric solutions are discussed. The facts that Schwarzschild’s spacetime is not a solution to the corresponding equations of motion and Birkhoﬀ’s theorem validity are analyzed and some consequences worked out.

We study the response of a static Unruh-DeWitt detector outside an exotic compact object (ECO) with a general reflective boundary condition in 3+1 dimensions. The horizonless ECO, whose boundary is…

Primordial black holes that survive until the present have been considered as a dark matter candidate. In this paper we argue that primordial 2-2-hole remnants provide a more promising and testable…
