Exotic superfluidity in cold atoms | | Elena Gubankova
; | | Date: |
15 Jun 2009 | | Abstract: | We derived the low energy effective action for the collective modes in
asymmetric fermionic systems with attractive interaction. We obtained the phase
diagram in terms of the chemical potentials. It features a stable gapless
superfluidity with one Fermi surface on the BEC side of the resonance. Also we
predict a sharp increase in outer core of a vortex, i.e. vortex size, upon
entering into the gapless phase. This may serve as a signature of a gapless
phase. | | Source: | arXiv, 0906.2580 | | Services: | Forum | Review | PDF | Favorites | |
