Four-wave mixing and enhanced analogue Hawking effect in a nonlinear optical waveguide
Scott Robertson, Charles Ciret, Serge Massar +2
We study in detail the scattering of light on a soliton propagating in a waveguide which has been proposed as an experimental system in which one could observe the analogue Hawking…
Nonlinearities induced by parametric resonance in effectively 1D atomic Bose condensates
Scott Robertson, Florent Michel, Renaud Parentani
We present a numerical study of the dynamical effects following a sudden change of the transverse trapping frequency in an elongated Bose-Einstein condensate, which induces periodi…
Gravity waves on modulated flows downstream from an obstacle: The transcritical case
Florent Michel, Renaud Parentani, Scott Robertson
Periodic spatial variations of some parameter arise in analogue gravity experiments aimed at detecting the analogue version of the Hawking effect in a white hole flow. Having the s…
Assessing degrees of entanglement of phonon states in atomic Bose gases through the measurement of commuting observables
Scott Robertson, Florent Michel, Renaud Parentani
We show that measuring commuting observables can be sufficient to assess that a bipartite state is entangled according to either nonseparability or the stronger criterion of 'steer…
Controlling and observing nonseparability of phonons created in time-dependent 1D atomic Bose condensates
Scott Robertson, Florent Michel, Renaud Parentani
We study the spectrum and entanglement of phonons produced by temporal changes in homogeneous one-dimensional atomic condensates. To characterize the experimentally accessible chan…
Phonon spectrum and correlations in a transonic flow of an atomic Bose gas
Florent Michel, Jean-François Coupechoux, Renaud Parentani
Motivated by a recent experiment of J.~Steinhauer, we reconsider the spectrum and the correlations of the phonons spontaneously emitted in stationary transonic flows. The latter ar…
