Sonic black holes with thick horizons in BECs
Daniel Peñalver, Marco De Vito, Roberto Balbinot +1
The paper studies one‑dimensional acoustic black holes in Bose‑Einstein condensates that have an extended region where the flow speed equals the speed of sound, effectively creatin…
Quantum backreaction in an analog black hole
G. Ciliberto, R. Balbinot, A. Fabbri +1
We extend the Gross-Pitaevskii equation to incorporate the effect of quantum fluctuations onto the flow of a weakly interacting Bose-Einstein condensate. Applying this framework to…
Backreaction equations for 1+1 dimensional BEC sonic black holes
Roberto Balbinot, Alessandro Fabbri, Giorgio Ciliberto +1
As in the gravitational context, one of the most challenging open question in analogue black holes formed in Bose-Einstein condensates concerns the backreaction of Hawking-like rad…
Some considerations on BEC analogue black holes
Roberto Balbinot, Alessandro Fabbri
In this paper, dedicated to the memory of A. Aurilia, we will review some basic features of Hawking's black hole radiation and compare them with the corresponding ones present in B…
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…
Looking for traces of Hawking radiation in correlation functions of BEC acoustic black holes
Paul R. Anderson, Roberto Balbinot, Richard A. Dudley +1
Renaud Parentani was one of the leading figures in Quantum Field Theory in curved spacetime, in particular concerning its applications to Hawking-like radiation in analogue models.…
