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…
Three-vortex configurations in trapped Bose-Einstein condensates
J. A. Seman, E. A. L. Henn, M. Haque +9
We report on the creation of three-vortex clusters in a Bose-Einstein condensate by oscillatory excitation of the condensate. This procedure can create vortices of both c…
Observation of vortex formation in an oscillating trapped Bose-Einstein condensate
E. A. L. Henn, J. A. Seman, E. R. F. Ramos +7
We report on the observation of vortex formation in a Bose-Einstein condensate of Rb-87 atoms. Vortices are generated by superimposing an oscillating excitation to the trapping pot…
Generation of nonground-state Bose-Einstein condensates by modulating atomic interactions
E. R. F. Ramos, E. A. L. Henn, J. A. Seman +5
A technique is proposed for creating nonground-state Bose-Einstein condensates in a trapping potential by means of the temporal modulation of atomic interactions. Applying a time-d…
Order parameter for the dynamical phase transition in Bose-Einstein condensates with topological modes
E. R. F. Ramos, L. Sanz, V. I. Yukalov +1
In a trapped Bose-Einstein condensate, subject to the action of an alternating external field, coherent topological modes can be resonantly excited. Depending on the amplitude of t…
Ramsey fringes formation during excitation of topological modes in a Bose-Einstein condensate
E. R. F. Ramos, L. Sanz, V. I. Yukalov +1
The Ramsey fringes formation during the excitation of topological coherent modes of a Bose-Einstein condensate by an external modulating field is considered. The Ramsey fringes app…
