Suppression of infrared instability in trans-sonic flows by condensation of zero-frequency short wave length phonons
Xavier Busch, Florent Michel, Renaud Parentani
We analyze the peculiar infrared instability that characterizes stationary inhomogeneous flows when their velocity crosses the sound speed by decreasing values. For definiteness, w…

Quantum entanglement in analogue Hawking radiation, when is the final state non-separable ?
Xavier Busch, Renaud Parentani
We study the quantum entanglement of the quasiparticle pairs emitted by analogue black holes. We use a phenomenological description of the spectra in dispersive media to study the…
