Taming higher-derivative interactions and bootstrapping gravity with soft theorems
Raúl Carballo-Rubio, Francesco Di Filippo, Nathan Moynihan
On-shell constructibility is redefining our understanding of perturbative quantum field theory. The tree-level S-matrix of constructible theories is completely determined by a set…
Topological Features of the Quantum Vacuum
Stephon Alexander, Raúl Carballo-Rubio
A central aspect of the cosmological constant problem is to understand why vacuum energy does not gravitate. In order to account for this observation, while allowing for nontrivial…
Phenomenological aspects of black holes beyond general relativity
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +1
While singularities are inevitable in the classical theory of general relativity, it is commonly believed that they will not be present when quantum gravity effects are taken into…
On the viability of regular black holes
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati +2
The evaporation of black holes raises a number of conceptual issues, most of them related to the final stages of evaporation, where the interplay between the central singularity an…
The Unruh effect without thermality
Raul Carballo-Rubio, Luis J. Garay, Eduardo Martin-Martinez +1
We show that uniformly accelerated detectors can display genuinely thermal features even if the Kubo-Martin-Schwinger (KMS) condition fails to hold. These features include satisfyi…
Observational evidence for the formation of trapping horizons in astrophysical black holes
Raúl Carballo-Rubio, Pawan Kumar, Wenbin Lu
Black holes in general relativity are characterized by their trapping horizon, a one-way membrane that can be crossed only inwards. The existence of trapping horizons in astrophysi…
Minimally modified theories of gravity: a playground for testing the uniqueness of general relativity
Raúl Carballo-Rubio, Francesco Di Filippo, Stefano Liberati
In a recent paper [1], it was introduced a new class of gravitational theories with two local degrees of freedom. The existence of these theories apparently challenges the distinct…
