Nonexistence of a parent theory for general relativity and unimodular gravity
Gerardo García-Moreno, Alejandro Jiménez Cano
General Relativity (GR) and Unimodular Gravity (UG) provide two equivalent descriptions of gravity that differ in the nature of the cosmological constant. While GR is based on the…
Hawking radiation from an analogue bouncing geometry
Alberto García Martín-Caro, Gerardo García-Moreno, Javier Olmedo +1
We propose a setting that simulates Hawking radiation from an analogue bouncing geometry, i.e., a collapsing geometry that reverts its collapse after a finite time, in a setup cons…
Bootstrapping gravity and its extension to metric-affine theories
Adrià Delhom, Gerardo García-Moreno, Manuel Hohmann +2
In this work we study diffeomorphism-invariant metric-affine theories of gravity from the point of view of self-interacting field theories on top of Minkowski spacetime (or other b…
Unimodular Gravity vs General Relativity: A status report
Raúl Carballo-Rubio, Luis J. Garay, Gerardo García-Moreno
Unimodular Gravity is an alternative to General Relativity (GR) which, however, is so closely related to the latter that one can wonder to what extent they are different. The diffe…
Chronology Protection Implementation in Analogue Gravity
Carlos Barceló, Jokin Eguia Sánchez, Gerardo García-Moreno +1
Analogue gravity systems offer many insights into gravitational phenomena, both at the classical and at the semiclassical level. The existence of an underlying Minkowskian structur…
Analogue gravity simulation of superpositions of spacetimes
Carlos Barceló, Luis J. Garay, Gerardo García-Moreno
Taking the principles of quantum mechanics as they stand and applying them to gravity, leads to the conclusion that one might be able to generate superpositions of spacetimes, at l…
