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 $\sigma (k)=4\pi /k^2$, with $\hslash k$…
