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…
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…
Coherent coupling of momentum states: selectivity and phase control
Charlie Leprince, Victor Gondret, Clothilde Lamirault +4
We demonstrate the effect of pulse shaping in momentum selective atomic Bragg diffraction. We compare temporal square pulses, which produce sidelobes in momentum space, with other…
Sub-shot-noise interferometry with two-mode quantum states
Quentin Marolleau, Charlie Leprince, Victor Gondret +2
We study the feasibility of sub-shot-noise interferometry with imperfect detectors, starting from twin-Fock states and two mode squeezed vacuum states. We derive analytical express…
Persistent current formation in double-ring geometries
Thomas Bland, Quentin Marolleau, Paolo Comaron +2
Quenching an ultracold bosonic gas in a ring across the Bose-Einstein condensation phase transition is known, and has been experimentally observed, to lead to the spontaneous emerg…
