Quantum state of interacting primordial inhomogeneities: de-squeezing and decoherence
Amaury Micheli, Yuto Oshima, Tomo Takahashi
We investigate how interactions affect the quantum state of scalar perturbations during inflation and the quantum correlations they may exhibit. Focusing on the case of scalar pert…
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…
