摘要
We have created quantum degenerate Fermi gases of Li-6 atoms at unprecedented high densities exceeding 1/(lambda) over bar (3) (where lambda is the wavelength of resonant light). In this regime, new optical properties are predicted. Spin-polarized Fermi gases are usually regarded as noninteracting due to the weakness of p-wave interactions. Here we study the properties of " p-wave matter," where elastic and inelastic p-wave collisions determine the dynamics of the system. We characterize thermalization, evaporative cooling, and inelastic two-body and three-body collisions. P-wave dipolar relaxation creates a metastable mixture of the lowest and highest hyperfine states.
