Bose-Einstein condensates near a microfabricated surface
A. E. Leanhardt, Y. Shin, A. P. Chikkatur +3
Magnetically and optically confined Bose-Einstein condensates were studied near a microfabricated surface. Condensate fragmentation observed in microfabricated magnetic traps was n…
Sodium Bose-Einstein Condensates in the F=2 State in a Large-volume Optical Trap
A. Görlitz, T. L. Gustavson, A. E. Leanhardt +6
We have investigated the properties of Bose-Einstein condensates of sodium atoms in the upper hyperfine ground state in a purely optical trap. Condensates in the high-field seeking…
Topological vortex formation in a Bose-Einstein condensate
A. E. Leanhardt, A. Görlitz, A. P. Chikkatur +4
Vortices were imprinted in a Bose-Einstein condensate using topological phases. Sodium condensates held in a Ioffe-Pritchard magnetic trap were transformed from a non-rotating stat…
Propagation of Bose-Einstein condensates in a magnetic waveguide
A. E. Leanhardt, A. P. Chikkatur, D. Kielpinski +4
Gaseous Bose-Einstein condensates of 2-3 million atoms were loaded into a microfabricated magnetic trap using optical tweezers. Subsequently, the condensates were released into a m…
Transport of Bose-Einstein Condensates with Optical Tweezers
T. L. Gustavson, A. P. Chikkatur, A. E. Leanhardt +4
We have transported gaseous Bose-Einstein condensates over distances up to 44 cm. This was accomplished by trapping the condensate in the focus of an infrared laser and translating…
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…
