We subject a falling cloud of cold cesium atoms to periodic kicks from a sinusoidal potential created by a vertical standing wave of laser light. By controllably accelerating the potential, we show quantum accelerator mode dynamics to be highly sensi... Read More about Gravity-sensitive quantum dynamics in cold atoms.

Adiabatic association of ultracold molecules via magnetic-field tunable interactions (2004)
Journal Article
Góral, K., Köhler, T., Gardiner, S., Tiesinga, E., & Julienne, P. (2004). Adiabatic association of ultracold molecules via magnetic-field tunable interactions. Journal of Physics B: Atomic, Molecular and Optical Physics, 37(17), 3457-3500. https://doi.org/10.1088/0953-4075/37/17/006

We consider in detail the situation of applying a time-dependent external magnetic field to a 87Rb atomic Bose–Einstein condensate held in a harmonic trap, in order to adiabatically sweep the interatomic interactions across a Feshbach resonance to pr...

Decoherence of Bose-Einstein condensates in microtraps. (2004)
Journal Article

We discuss the impact of thermally excited near fields on the coherent expansion of a condensate in a miniaturized electromagnetic trap. Monte Carlo simulations are compared with a kinetic two-component theory and indicate that atom interactions can... Read More about Decoherence of Bose-Einstein condensates in microtraps..

(De)coherence Physics With Condensates In Microtraps (2004)
Journal Article
Henkel, C., Gardiner, S., & Negretti, A. (2004). (De)coherence Physics With Condensates In Microtraps. Laser Physics, 14(4), 615-620

We discuss the dynamics of a condensate in a miniaturized electromagnetic trap formed above a microstructured substrate. Recent experiments have found that trap lifetimes get reduced when approaching the substrate because atoms couple to thermally ex...
