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…
Optimal control of complex atomic quantum systems
S. van Frank, M. Bonneau, J. Schmiedmayer +8
Quantum technologies will ultimately require manipulating many-body quantum systems with high precision. Cold atom experiments represent a stepping stone in that direction: a high…
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…
The 2nd order coherence of superradiance from a Bose--Einstein condensate
Raphael Lopes, Almazbek Imanaliev, Marie Bonneau +4
We have measured the 2-particle correlation function of atoms from a Bose--Einstein condensate participating in a superradiance process, which directly reflects the 2nd order coher…
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.…
