Formation and Decay of Vortex Lattices in Bose-Einstein Condensates at Finite Temperatures
J. R. Abo-Shaeer, C. Raman, W. Ketterle
The dynamics of vortex lattices in stirred Bose-Einstein condensates have been studied at finite temperatures. The decay of the vortex lattice was observed non-destructively by mon…
Vortex Nucleation in a Stirred Bose-Einstein Condensate
C. Raman, J. R. Abo-Shaeer, J. M. Vogels +2
We studied the nucleation of vortices in a Bose-Einstein condensate stirred by a laser beam. We observed the vortex cores using time-of-flight absorption imaging. By varying the si…
Realization of Bose-Einstein condensates in lower dimensions
A. Gorlitz, J. M. Vogels, A. E. Leanhardt +9
Bose-Einstein condensates of sodium atoms have been prepared in optical and magnetic traps in which the energy-level spacing in one or two dimensions exceeds the interaction energy…
