Sonic analog of gravitational black holes in Bose-Einstein condensates
Trapped bosons at ultralow temperature can provide an analog to a black-hole spacetime. Bose-Enstein condensates is an especially powerful tool for this kind of investigation. To demonstrate this, the case of a condensate in a ring trap is considered as an example. Further, a realistic scheme for ad...

| Summary: | Trapped bosons at ultralow temperature can provide an analog to a black-hole spacetime. Bose-Enstein condensates is an especially powerful tool for this kind of investigation. To demonstrate this, the case of a condensate in a ring trap is considered as an example. Further, a realistic scheme for adiabatically creating stable sonic black/white holes is proposed. © 2000 The American Physical Society |
