Emergent gravity: the BEC paradigm
Gil Jannes
We study selected aspects of quantum gravity phenomenology inspired by the gravitational analogy in Bose--Einstein condensates (BECs). We first review the basic ideas and formalism…
Some comments on "The Mathematical Universe"
Gil Jannes
I discuss some problems related to extreme mathematical realism, focusing on a recently proposed "shut-up-and-calculate" approach to physics (arXiv:0704.0646, arXiv:0709.4024). I o…
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…
A real Lorentz-FitzGerald contraction
Carlos Barcelo, Gil Jannes
Many condensed matter systems are such that their collective excitations at low energies can be described by fields satisfying equations of motion formally indistinguishable from t…
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…
