Phys. Rev. Lett. 98, 020603 (2007) [4 pages]Derivation of Hydrodynamics for the Gapless Mode in the BEC-BCS Crossover from the Exact One-Loop Effective ActionReceived 7 August 2006; published 10 January 2007 We derive generalized two-superfluid continuity equations for the BEC-BCS crossover in the presence of a Feshbach resonance at T=0. In addition, we calculate the velocity of sound throughout both BCS and Bose-Einstein condensation (BEC) regimes. © 2007 The American Physical Society URL:
