Mechanism of stimulated Hawking radiation in a laboratory Bose-Einstein condensate
Mechanism of stimulated Hawking radiation in a laboratory Bose-Einstein condensate
We model a sonic black hole analog in a quasi one-dimensional Bose-Einstein condensate, using a Gross-Pitaevskii equation matching the configuration of a recent experiment by Steinhauer [Nat. Phys. 10, 864 (2014)]. The model agrees well with important features of the experimental observations, demonstrating their hydrodynamic nature. We find that a …
