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…
Van der Waals chain: a simple model for Casimir forces in dielectrics
H. Horner, L. M. Rachbauer, S. Rotter +1
The Casimir force between dielectric bodies is well-understood, but not the Casimir force inside a dielectric, in particular its renormalization. We develop and analyse a simple mo…
Casimir stress in an inhomogeneous medium
T. G. Philbin, C. Xiong, U. Leonhardt
The Casimir effect in an inhomogeneous dielectric is investigated using Lifshitz's theory of electromagnetic vacuum energy. A permittivity function that depends continuously on one…
No quantum friction between uniformly moving plates
T. G. Philbin, U. Leonhardt
The Casimir forces between two plates moving parallel to each other are found by calculating the vacuum electromagnetic stress tensor. The perpendicular force between the plates is…
Notes on Conformal Invisibility Devices
Ulf Leonhardt
As a consequence of the wave nature of light, invisibility devices based on isotropic media cannot be perfect. The principal distortions of invisibility are due to reflections and…
