Induced interactions and the superfluid transition temperature in a three-component Fermi gas
arXiv:0908.3733 · doi:10.1103/PhysRevLett.103.260403
Abstract
We study many-body contributions to the effective interaction between fermions in a three-component Fermi mixture. We find that effective interactions induced by the third component can lead to a phase diagram different from that predicted if interactions with the third component are neglected. As a result, in a confining potential a superfluid shell structure can arise even for equal populations of the components. We also find a critical temperature for the BCS transition in a 6Li mixture which can deviate strongly from the one in a weakly interacting two-component system.
