Scale Holography
Jose A. R. Cembranos, Salvador E. R. Ciarreta, Luis J. Garay
We present a new correspondence between a d-dimensional dynamical system and a whole family of (d+1)-dimensional systems. This new scale-holographic relation is built by the explic…
From physical symmetries to emergent gauge symmetries
Carlos Barceló, Raúl Carballo-Rubio, Francesco Di Filippo +1
Gauge symmetries indicate redundancies in the description of the relevant degrees of freedom of a given field theory and restrict the nature of observable quantities. One of the pr…
Hawking versus Unruh effects, or the difficulty of slowly crossing a black hole horizon
Luis C. Barbado, Carlos Barceló, Luis J. Garay +1
When analyzing the perception of Hawking radiation by different observers, the Hawking effect becomes mixed with the Unruh effect. The separation of both effects is not always clea…
Thermalization of particle detectors: The Unruh effect and its reverse
Luis J. Garay, Eduardo Martin-Martinez, Jose de Ramon
We study the Anti-Unruh effect in general stationary scenarios. We find that, for accelerated trajectories, a particle detector coupled to a KMS state of a quantum field can cool d…
Exponential fading to white of black holes in quantum gravity
Carlos Barceló, Raúl Carballo-Rubio, Luis J. Garay
Quantization of the gravitational field may allow the existence of a decay channel of black holes into white holes with an explicit time-reversal symmetry. The definition of a mean…
A tensorial description of particle perception in black-hole physics
Luis C. Barbado, Carlos Barceló, Luis J. Garay +1
In quantum field theory in curved backgrounds, one typically distinguishes between objective, tensorial, quantities such as the Renormalized Stress-Energy Tensor (RSET) and subject…
