Sonic black holes with thick horizons in BECs
Daniel Peñalver, Marco De Vito, Roberto Balbinot +1
We consider simple one dimensional models of acoustic black holes formed by Bose-Einstein condensates where the flow is stepwise homogeneous. We shall concentrate on the case in wh…

Acoustic black holes in BECs with an extended sonic region
Daniel Peñalver, Marco De Vito, Roberto Balbinot +1
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 transit…

The fine structure of the peaks of the correlation function in acoustic black holes: a complete analytical model
Paul R. Anderson, Roberto Balbinot, Richard A. Dudley +3
The detailed structure of the peaks appearing in the density-density correlation function for an acoustic black hole formed by a Bose-Einstein condensate is analytically discussed…
