Slow light in degenerate fermi gases.

Long-Lived Spin-Orbit-Coupled Degenerate Dipolar Fermi Gas

We describe the creation of a long-lived spin-orbit-coupled gas of quantum degenerate atoms using the most magnetic fermionic element, dysprosium. Spin-orbit coupling arises from a synthetic gauge field created by the adiabatic following of degenerate dressed states composed of optically coupled components of an atomic spin. Because of dysprosium’s large electronic orbital angular momentum and ...

Production of a degenerate Fermi gas of metastable helium-3 atoms

Most of this book discusses Fermi gases composed of alkali atoms. Since the first realization of a degenerate K Fermi gas in 1999, Li has been the only other fermionic atom to be cooled below the Fermi temperature. In this contribution we will discuss our recent results on cooling fermionic He below the Fermi temperature. This has not been performed with ground state He, but with He in the meta...

Degenerate Fermi Gases with p-wave interactions

Fiftyfold improvement in the number of quantum degenerate fermionic atoms.

We have produced a quantum degenerate 6Li Fermi gas with up to 7 x 10(7) atoms, an improvement by a factor of 50 over all previous experiments with degenerate Fermi gases. This was achieved by sympathetic cooling with bosonic 23Na in the F=2, upper hyperfine ground state. We have also achieved Bose-Einstein condensation of F=2 sodium atoms by direct evaporation.

Degenerate Fermi gases of ytterbium.

Evaporative cooling was performed to cool fermionic 173Yb atoms in a crossed optical dipole trap. The large elastic collision rate leads to efficient evaporation and we have successfully cooled the atoms to 0.37+/-0.06 of the Fermi temperature, that is to say, to a quantum degenerate regime. In this regime, a plunge of evaporation efficiency was observed as a result of Fermi degeneracy.
