ULTRACOLD MATTER:
The Quest for Superfluidity in Fermi Gases

Lev Pitaevskii and Sandro Stringari

Studies of ultracold atomic gases have focused on bosons--fundamental particles that have an integer spin and can form Bose-Einstein condensates. In their Perspective, Pitaevskii and Stringari discuss recent studies of the quantum behavior of fermion gases (with noninteger spin) at ultracold conditions. They highlight the report by O'Hara et al., whose realization and characterization of an ultracold Fermi gas sheds light on its quantum properties.

The authors are in the Dipartimento di Fisica, Universitá di Trento, and Istituto Nazionale per la Fisica della Materia, 38050 Povo, Italy. L. Pitaevskii is also at the Kapitza Institute for Physical Problems, ul. Kosygina 2, 117334 Moscow, Russia. E-mail: stringar{at}science.unitn.it, lev{at}science.unitn.it
