Phys. Rev. Lett. 87, 120406 (2001) [4 pages]Resonance Superfluidity in a Quantum Degenerate Fermi GasReceived 22 March 2001; published 31 August 2001 We consider the superfluid phase transition that arises when a Feshbach resonance pairing occurs in a dilute Fermi gas. We apply our theory to consider a specific resonance in potassium ( 40K), and find that for achievable experimental conditions, the transition to a superfluid phase is possible at the high critical temperature of about 0.5TF. Observation of superfluidity in this regime would provide the opportunity to experimentally study the crossover from the superfluid phase of weakly coupled fermions to the Bose-Einstein condensation of strongly bound composite bosons. © 2001 The American Physical Society URL:
