Systematic design study of all-optical delay line based on Brillouin scattering enhanced cascade coupled ring resonators
Myungjun Lee, Michael E. Gehm, Mark A. Neifeld
We present a technique to improve the slow-light performance of a side-coupled spaced sequence of resonators (SCISSOR) combined with a stimulated Brillouin scattering (SBS) gain me…
Evidence for Superfluidity in a Resonantly Interacting Fermi Gas
J. Kinast, S. L. Hemmer, M. E. Gehm +2
We observe collective oscillations of a trapped, degenerate Fermi gas of Li atoms at a magnetic field just above a Feshbach resonance, where the two-body physics does not suppo…
Unitarity-Limited Elastic Collision Rate in a Harmonically-Trapped Fermi Gas
M. E. Gehm, S. L. Hemmer, K. M. O'Hara +1
We derive the elastic collision rate for a harmonically-trapped Fermi gas in the extreme unitarity limit where the s-wave scattering cross section is , with …
Observation of a Strongly-Interacting Degenerate Fermi Gas of Atoms
K. M. O'Hara, S. L. Hemmer, M. E. Gehm +2
We report on the observation of a highly-degenerate, strongly-interacting Fermi gas of atoms. Fermionic Li atoms in an optical trap are evaporatively cooled to degeneracy using…
Mechanical Stability of a Strongly-Interacting Fermi Gas of Atoms
M. E. Gehm, S. L. Hemmer, S. R. Granade +2
A strongly-attractive, two-component Fermi gas of atoms exhibits universal behavior and should be mechanically stable as a consequence of the quantum mechanical requirement of unit…
Measurement of the Zero Crossing in a Feshbach Resonance of Fermionic 6-Li
K. M. O'Hara, S. L. Hemmer, S. R. Granade +5
We measure a zero crossing in the scattering length of a mixture of the two lowest hyperfine states of 6-Li. To locate the zero crossing, we monitor the decrease in temperature and…
