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…
Cosmology as a search for overall equilibrium
Carlos Barcelo
In this letter we will revise the steps followed by A. Einstein when he first wrote on cosmology from the point of view of the general theory of relativity. We will argue that his…
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…
A stable static Universe?
Carlos Barcelo, Grigory Volovik
Starting from the assumption that general relativity might be an emergent phenomenon showing up at low-energies from an underlying microscopic structure, we re-analyze the stabilit…
