Large atom number Bose-Einstein Condensate machines
Erik W Streed, Ananth P Chikkatur, Todd L Gustavson +6
We describe experimental setups for producing large Bose-Einstein condensates of 23Na and 87Rb. In both, a high flux thermal atomic beam is decelerated by a Zeeman slower and is ca…
Direct, Non-Destructive Imaging of Magnetization in a Spin-1 Bose Gas
J. M. Higbie, L. E. Sadler, S. Inouye +5
Polarization-dependent phase-contrast imaging is used to spatially resolve the magnetization of an optically trapped ultracold gas. This probe is applied to Larmor precession of de…
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…
