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 due to modulated Dynamical Casimir Effect
Xavier Busch, Renaud Parentani, Scott Robertson
We study the creation and entanglement of quasiparticle pairs due to a periodic variation of the mode frequencies of a homogeneous quantum system. Depending on the values of the pa…
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…
Spectrum and entanglement of phonons in quantum fluids of light
Xavier Busch, Iacopo Carusotto, Renaud Parentani
We study the quantum state of phonons propagating on top of a fluid of light coherently generated in a planar microcavity device by a quasi-resonant incident laser beam. In the ste…
Dynamical Casimir Effect in dissipative media: When is the final state non-separable ?
Xavier Busch, Renaud Parentani
We study the consequences of dissipation in homogeneous media when the system is subject to a sudden change, thereby producing pairs of correlated quasi-particles with opposite mom…
Dissipative fields in de Sitter and black hole spacetimes: Quantum entanglement due to pair production and dissipation
Julian Adamek, Xavier Busch, Renaud Parentani
For free fields, pair creation in expanding universes is associated with the building up of correlations that lead to nonseparable states, i.e., quantum mechanically entangled ones…
