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…
