The Mystery of the Ramsey Fringe that Didn't Chirp
D. M. Harber, H. J. Lewandowski, J. M. McGuirk +1
We use precision microwave spectroscopy of magnetically trapped, ultra-cold 87Rb to characterize intra- and inter-state density correlations. The cold collision shifts for both nor…
Effect of cold collisions on spin coherence and resonance shifts in a magnetically trapped ultra-cold gas
D. M. Harber, H. J. Lewandowski, J. M. McGuirk +1
We have performed precision microwave spectroscopy on ultra-cold Rb-87 confined in a magnetic trap, both above and below the Bose-condensation transition. The cold collision shifts…
Spatial resolution of spin waves in an ultra-cold gas
J. M. McGuirk, H. J. Lewandowski, D. M. Harber +3
We present the first spatially resolved images of spin waves in a gas. The complete longitudinal and transverse spin field as a function of time and space is reconstructed. Frequen…
