Title: Analogue Hawking radiation?
Abstract: The “analogue spacetime” programme uses various physical analogues (typically condensed matter analogues) to simulate kinematic aspects of general relativity — that is, curved spacetimes up to and including horizons, and free quantum fields defined thereupon, but not the dynamical Einstein equations. From a theoretical perspective this is enough to simulate Hawking radiation, (which is a  purely kinematic effect), but not Bekenstein entropy, (which is an intrinsically dynamic effect depending on the Einstein equations.) A number of experiments have now been carried out (surface waves on water, photons in nonlinear optics, phonons in Bose-Einstein condensates) that probe various aspects of the (analogue) Hawking radiation process. I will give a broad overview of the experiments performed to ate, salient points of the underlying theory, and discuss what we can and cannot learn from this analogue Hawking radiation effect.
