Hawking Radiation in Analogue Gravity

Abstract

The phenomenon of Hawking Radiation is explored in analogue gravity using Bose-Einstein Condensates. The process of spontaneous pair production that occurs at the event horizon is treated as a scattering problem, and the method of establishing Hawking Radiation using density correlations is reviewed. Based on the results obtained, the existing formalism is modified to incorporate the changes to the asymptotic modes due to the presence of the horizon.
