Black-Hole evaporation and quantum-depletion in Bose–Einstein condensates
Keyword(s):
We study the analogy between the Hawking radiation in Black-Holes and the quantum depletion process of a Bose–Einstein condensate by using the Bogoliubov transformations method. We find that the relation between the Bogoliubov coefficients is similar in both cases (in the appropriate regimes). We then connect the condensate variables with those associated to the Black-Hole, demonstrating then that the zero temperature regime of the condensate is equivalent to the existence of an event horizon in gravity.
