Observation of entanglement in a cold atom analog of cosmological preheating
Victor Gondret, Clothilde Lamirault, Rui Dias +8
We observe entanglement between collective excitations of a Bose-Einstein condensate in a configuration analogous to particle production during the preheating phase of the early un…

Parametric pair production of collective excitations in a Bose-Einstein condensate
Victor Gondret, Rui Dias, Clothilde Lamirault +7
By exciting the transverse breathing mode of an elongated Bose-Einstein condensate, we parametrically produce longitudinal collective excitations in a pairwise manner. This process…

Dissipative parametric resonance in a modulated 1D Bose gas
Amaury Micheli, Scott Robertson
We synthesize results of previous works to give a coherent and self-consistent account of parametric resonance in a modulated quasi-1D Bose gas in the presence of a dissipative mec…
