Collective excitation of a Bose-Einstein condensate by modulation of the atomic scattering length
S. E. Pollack, D. Dries, R. G. Hulet +5
We excite the lowest-lying quadrupole mode of a Bose-Einstein condensate by modulating the atomic scattering length via a Feshbach resonance. Excitation occurs at various modulatio…
Dissipative Transport of a Bose-Einstein Condensate
D. Dries, S. E. Pollack, J. M. Hitchcock +1
We investigate the effects of impurities, either correlated disorder or a single Gaussian defect, on the collective dipole motion of a Bose-Einstein condensate of Li in an opti…
Universality in Three- and Four-Body Bound States of Ultracold Atoms
Scott E. Pollack, Daniel Dries, Randall G. Hulet
Under certain circumstances, three or more interacting particles may form bound states. While the general few-body problem is not analytically solvable, the so-called Efimov trimer…
Extreme tunability of interactions in a Li Bose-Einstein condensate
Scott E. Pollack, D. Dries, M. Junker +3
We use a Feshbach resonance to tune the scattering length a of a Bose-Einstein condensate of 7Li in the |F = 1, m_F = 1> state. Using the spatial extent of the trapped condensate w…
Photoassociation of a Bose-Einstein Condensate near a Feshbach Resonance
M. Junker, D. Dries, C. Welford +3
We measure the effect of a magnetic Feshbach resonance (FR) on the rate and light-induced frequency shift of a photoassociation resonance in ultracold Li. The photoassociation-…
Phase Coherence and Superfluid-Insulator Transition in a Disordered Bose-Einstein Condensate
Yong P. Chen, J. Hitchcock, D. Dries +3
We have studied the effects of a disordered optical potential on the transport and phase coherence of a Bose-Einstein condensate (BEC) of 7Li atoms. At moderate disorder strengths…
