Mimicking black holes in fluidsAntonin Coutant (Université de Nottingham, Royaume-Uni)
Thursday 09 November 2017 14:00 - Tours - Salle 1180 (Bât E2)
Résumé :
I will discuss the possibility to mimic black hole physics in fluid flows. The starting point is an analogy discovered by Unruh between the propagation of sound in a flowing fluid and waves around a black hole. I will discuss the analogue of the Hawking effect, and the entanglement properties of the Hawking particle and its partner. I will also present a recent water wave experiment, where we have observed the analogue of black hole superradiance, that is, the amplification of waves by extraction of angular momentum from a rotating flow.
