Relaxation, chaos, and thermalization in a three-mode model of a BEC
M. A. Garcia-March, S. van Frank, M. Bonneau +3
We study the complex quantum dynamics of a system of many interacting atoms in an elongated anharmonic trap. The system is initially in a Bose-Einstein condensed state, well descri…
Characterizing twin-particle entanglement in double-well potentials
Marie Bonneau, William J. Munro, Kae Nemoto +1
We consider a pair of twin atoms trapped in double-well potentials. For each atom, two orthogonal spatial modes are accessible: the states and spatially lo…
Anisotropy in s-wave Bose-Einstein condensate collisions and its relationship to superradiance
Piotr Deuar, Jean-Christophe Jaskula, Marie Bonneau +4
We report the experimental realization of a single-species atomic four-wave mixing process with BEC collisions for which the angular distribution of scattered atom pairs is not iso…
Tunable source of correlated atom beams
Marie Bonneau, Josselin Ruaudel, Raphaël Lopes +4
We use a one-dimensional optical lattice to modify the dispersion relation of atomic matter waves. Four-wave mixing in this situation produces atom pairs in two well defined beams.…
An acoustic analog to the dynamical Casimir effect in a Bose-Einstein condensate
Jean-Christophe Jaskula, Guthrie B. Partridge, Marie Bonneau +4
We have realized an acoustic analog to the Dynamical Casimir effect. The density of a trapped Bose-Einstein condensate is modulated by changing the trap stiffness. We observe the c…
Sub-Poissonian number differences in four-wave mixing of matter waves
Jean-Christophe Jaskula, Marie Bonneau, Guthrie B. Partridge +6
We demonstrate sub-Poissonian number differences in four-wave mixing of Bose-Einstein condensates of metastable helium. The collision between two Bose-Einstein condensates produces…
