Optical time travel: proposal for testing Hawking's Chronology Protection Conjecture in an optical analogue
D. Bermudez, U. Leonhardt
Classical general relativity allows time travel, but Hawking [Phys. Rev. D 46, 603 (1992)] conjectured that quantum mechanics ultimately prevents it. Here we propose a feasible exp…
Backreaction of stimulated Hawking radiation in an optical analogue
Lorenzo M. Procopio, Raul Aguero-Santacruz, David Bermudez +1
Hawking radiation - the emission of quantum particles at the event horizon of a black hole - connects gravity with quantum mechanics and thermodynamics; the Bekenstein-Hawking entr…
Analogue Hawking radiation in nonlinear quantum optics
Isaac Bernal, Miguel A. Cortés-Ortiz, David Bermudez
The Hawking effect can be understood as a broad kinematic phenomenon associated with mode behavior near a horizon. While astrophysical black holes produce one specific realization…
Optical analogue of the Schwarzschild-Planck metric
Alhan Moreno-Ruiz, David Bermudez
We revisit the connection between trajectories of accelerated mirrors and spacetime metrics. We present the general (1+1)D effective metric that can be obtained with a fibre-optica…
Hawking radiation in optics and beyond
Raul Aguero-Santacruz, David Bermudez
Hawking radiation was originally proposed in astrophysics, but it has been generalized and extended to other physical systems receiving the name of analogue Hawking radiation. In t…
Instabilities in an optical black-hole laser
Juan David Rincon-Estrada, David Bermudez
The Hamiltonian of optical fields in a nonlinear dispersive fiber is studied. Quantum field fluctuations are spontaneously created close to an optical event horizon through the ana…
