Phys. Rev. Lett. 101, 090402 (2008) [4 pages]Critical Temperature Curve in BEC-BCS CrossoverReceived 20 May 2008; published 27 August 2008 The strongly correlated regime of the crossover from Bardeen-Cooper-Schrieffer pairing to Bose-Einstein condensation can be realized by diluting a system of two-component fermions with a short-range attractive interaction. We investigate this system via a novel continuous-space-time diagrammatic determinant Monte Carlo method and determine the universal curve Tc/εF for the transition temperature between the normal and the superfluid states as a function of the scattering length with the maximum on the Bose-Einstein condensation side. At unitarity, we confirm that Tc/εF=0.152(7). © 2008 The American Physical Society URL:
