Periodic spin textures in a degenerate F=1 Rb spinor Bose gas
M. Vengalattore, J. Guzman, S. Leslie +2
We report on the spin textures produced by cooling unmagnetized Rb F=1 spinor gases into the regime of quantum degeneracy. At low temperatures, magnetized textures form that…
High-Resolution Magnetometry with a Spinor Bose-Einstein Condensate
M. Vengalattore, J. M. Higbie, S. R. Leslie +3
We demonstrate a precision magnetic microscope based on direct imaging of the Larmor precession of a Rb spinor Bose-Einstein condensate. This magnetometer attains a field se…
Coherence-enhanced imaging of a degenerate Bose gas
L. E. Sadler, J. M. Higbie, S. R. Leslie +2
We present coherence-enhanced imaging, an in situ technique that uses Raman superradiance to probe the spatial coherence properties of an ultracold gas. Applying this method, we ob…
Long Phase Coherence Time and Number Squeezing of two Bose-Einstein Condensates on an Atom Chip
G. -B. Jo, Y. Shin, S. Will +6
We measured the relative phase of two Bose-Einstein condensates confined in an radio frequency induced double well potential on an atom chip. We observed phase coherence between th…
Interference of Bose-Einstein Condensates on an Atom Chip
Y. Shin, C. Sanner, G. -B. Jo +6
We have used a microfabricated atom chip to split a single Bose-Einstein condensate of sodium atoms into two spatially separated condensates. Dynamical splitting was achieved by de…
Dynamical Instability of a Doubly Quantized Vortex in a Bose-Einstein condensate
Y. Shin, M. Saba, M. Vengalattore +6
Doubly quantized vortices were topologically imprinted in Na condensates, and their time evolution was observed using a tomographic imaging technique. The decay into…
