Phys. Rev. D 68, 114016 (2003) [5 pages]Breached pairing superfluidity at finite temperature and densityReceived 21 July 2003; published 30 December 2003 A general analysis of fermion pairing at finite temperature and density between different species with mismatched Fermi surfaces is presented. Very different from the temperature effect of the BCS phase, the recently found breached pairing phase resulted from the density difference of the two species lying in a region with calabashlike shape in the T-μ plane, and the most probable temperature for the new phase’s creation is finite but not zero. © 2003 The American Physical Society URL:
