Sensitivity of Hawking radiation to superluminal dispersion relations
C. Barcelo, L. J. Garay, G. Jannes
We analyze the Hawking radiation process due to collapsing configurations in the presence of superluminal modifications of the dispersion relation. With such superluminal dispersio…

Quasi-normal mode analysis in BEC acoustic black holes
C. Barcelo, A. Cano, L. J. Garay +1
We perform a quasi-normal mode analysis of black hole configurations in Bose-Einstein condensates (BEC). In this analysis we use the full Bogoliubov dispersion relation, not just t…

Stability analysis of sonic horizons in Bose-Einstein condensates
C. Barcelo, A. Cano, L. J. Garay +1
We examine the linear stability of various configurations in Bose-Einstein condensates with sonic horizons. These configurations are chosen in analogy with gravitational systems wi…
