Classical and quantum field theory in a box with moving boundaries: A numerical study of the Dynamical Casimir Effect
Alberto García Martín-Caro, Gerardo García-Moreno, Javier Olmedo +1
We present a detailed description of a quantum scalar field theory within a flat spacetime confined to a cavity with perfectly reflecting moving boundaries. Moreover, we establish…

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…
