Hawking Radiation on an Ion Ring in the Quantum Regime
arXiv:1008.3494 · doi:10.1088/1367-2630/13/4/045008 10.1088/1367-2630/13/6/069601
Abstract
This paper discusses a recent proposal for the simulation of acoustic black holes with ions. The ions are rotating on a ring with an inhomogeneous, but stationary velocity profile. Phonons cannot leave a region, in which the ion velocity exceeds the group velocity of the phonons, as light cannot escape from a black hole. The system is described by a discrete field theory with a nonlinear dispersion relation. Hawking radiation is emitted by this acoustic black hole, generating entanglement between the inside and the outside of the black hole. We study schemes to detect the Hawking effect in this setup.
