Deformation quantization in FLRW geometries
Alfonso F. Bobadilla, Jose A. R. Cembranos
We investigate the application of deformation quantization to the system of a free particle evolving within a universe described by a Friedmann-Lemaitre-Robertson-Walker (FLRW) geo…
The Wigner formalism on black hole geometries
David Garcia-Garcia, Jose A. R. Cembranos
This work explores the intersection of quantum mechanics and curved spacetime by employing the Wigner formalism to investigate quantum systems in the vicinity of black holes. Speci…
Gravitational and electromagnetic Cherenkov radiation constraints in modified dispersion relations
Mikel Artola, José A. R. Cembranos, Prado Martín-Moruno
Motivated by different approaches to quantum gravity, one could consider that Lorentz invariance is not an exact symmetry of nature at all energy scales. Following this spirit, mod…
Scalar Dark Matter Production through the Bubble Expansion Mechanism:The Role of the Lorentz factor and Non-Renormalizable Interactions
Jose A. R. Cembranos, Jesús Luque, Javier Rubio
We consider a Bubble Expansion mechanism for the production of scalar dark matter during a first-order phase transition in the very early Universe. Seeking for a dark matter energy…
Detecting dark matter oscillations with gravitational waveforms
Philippe Brax, Clare Burrage, Jose A. R. Cembranos +1
We consider the phase shift in the gravitational wave signal induced by fast oscillations of scalar dark matter surrounding binary systems, which could be probed by the future expe…
