High-Temperature Superfluidity in an Ultracold Fermi Gas — •Martin Zwierlein, Jamil Abo-Shaeer, André Schirotzek, Christian Schunck, and Wolfgang Ketterle — Department of Physics, MIT-Harvard Center for Ultracold Atoms, and Research Laboratory of Electronics, MIT, 77 Massachusetts Avenue, Cambridge, MA 02139, USA

Quantum degenerate atomic Fermi gases provide a remarkable opportunity to study strongly interacting Fermions. In contrast to other Fermi systems, such as superconductors, neutron stars or the quark-gluon plasma of the early Universe, these gases have low densities and their interactions can be precisely controlled over an enormous range. Our recent observation of vortex lattices in a rotating Fermi gas provides definitive evidence for superfluidity in these systems. Scaled to the density of electrons in a solid, this new form of superfluidity would occur already above room temperature.
