Non-local density correlations as signal of Hawking radiation in BEC acoustic black holes
Roberto Balbinot, Alessandro Fabbri, Serena Fagnocchi +2
We have used the analogy between gravitational systems and non-homogeneous fluid flows to calculate the density-density correlation function of an atomic Bose-Einstein condensate i…

The depletion in Bose Einstein condensates using Quantum Field Theory in curved space
Roberto Balbinot, Serena Fagnocchi, Alessandro Fabbri
Using methods developed in Quantum Field Theory in curved space we can estimate the effects of the inhomogeneities and of a non vanishing velocity on the depletion of a Bose Einste…
