Critical Temperature and Condensate Fraction of a Fermion Pair Condensate
arXiv:0712.1445 · doi:10.1103/PhysRevLett.101.180406
Abstract
We report on measurements of the critical temperature and the temperature dependence of the condensate fraction for a fermion pair condensate of 6Li atoms. The Bragg spectroscopy is employed to determine the critical temperature and the condensate fraction after a fast magnetic field ramp to the molecular side of the Feshbach resonance. Our measurements reveal the level-off of the critical temperature and the limiting behavior of condensate fraction near the unitarity limit.
