Abstract
We report the first quantum degenerate dipolar Fermi gas, the realization of which opens a new frontier for exploring strongly correlated physics and, in particular, quantum liquid crystalline phases. A quantum degenerate Fermi gas of the most magnetic atom is produced by laser cooling to before sympathetically cooling with ultracold, bosonic . The temperature of the spin-polarized is a factor below the Fermi temperature . The cotrapped concomitantly cools to approximately for Bose-Einstein condensation, thus realizing a novel, nearly quantum degenerate dipolar Bose-Fermi gas mixture. Additionally, we achieve the forced evaporative cooling of spin-polarized without to . That such a low temperature ratio is achieved may be a first signature of universal dipolar scattering.
