Quantum entanglement of Hawking-Partner modes in expanding cavities
José Manuel Montes-Armenteros, Javier Olmedo
This article investigates quantum entanglement generated within a one-dimensional cavity where one boundary undergoes prescribed acceleration, a setup designed to mimic aspects of…

Duality Symmetry and Anomaly for Gravitational Waves in Curved Spacetime
Adrian del Rio, Javier Olmedo, António Torres Manso
The vacuum Einstein equations admit a formulation closely analogous to the source-free Maxwell theory. In particular, the linearized equations exhibit an electric-magnetic duality…

Robustness of analogue Hawking radiation in cavities with moving boundaries
Alberto GarcÃa MartÃn-Caro, Javier Olmedo, Jose M. Sánchez Velázquez
In this work we explore the limitations and robustness of thermal radiation in dynamical Casimir systems serving as analogs for Hawking radiation. Through detailed numerical analys…
