Phonon decay in 1D atomic Bose quasicondensates via Beliaev-Landau damping
Amaury Micheli, Scott Robertson
In a 1D Bose gas, there is no non-trivial scattering channel involving three Bogoliubov quasiparticles that conserves both energy and momentum. Nevertheless, we show that such 3-wa…
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…
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…
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…
