    Hawking effect in BECs acoustic white holes

    Bogoliubov pseudoparticle creation in a BEC undergoing a WH-like flow is investigated analytically in the case of a one-dimensional geometry with stepwise homogeneous regions. Comparison of the results with th...

    Density correlations and analog dynamical Casimir emission of Bogoliubov phonons in modulated atomic Bose-Einstein condensates

    We present a theory of the density correlations that appear in an atomic Bose-Einstein condensate as a consequence of the emission of correlated pairs of Bogoliubov phonons by a time-dependent atom-atom scatte...

    Hawking radiation from acoustic black holes, short distance and backreaction effects

    Using the action principle we first review how linear density per¬turbations (sound waves) in an Eulerian fluid obey a relativistic equation: the d’Alembert equation. This analogy between propagation of sound ...

    A Planck-Like Problem for Quantum Charged Black Holes

    Motivated by the parallelism existing between the puzzles of classical physics at the beginning of the XXth century and the current paradoxes in the search of a quantum theory of gravity, we give, in analogy w...
