Acoustic black holes in BECs with an extended sonic region
arXiv:2504.08564 · doi:10.1103/hvph-mzqs
Abstract
In the context of Hawking-like radiation in sonic black holes formed by BECs we investigate the modifications of the emission spectrum caused by a finite width of the sonic transition region connecting the subsonic to supersonic flow.
