Leggett mode in a two-component Fermi gas with dipolar interactions
Leggett mode in a two-component Fermi gas with dipolar interactions
We develop an effective field theory to understand collective modes of a three-dimensional two-component Fermi superfluid with dipolar interparticle interactions, which are modeled by an idealized separable potential. We first examine the phase transition of the system at zero temperature, as the fermionic superfluidity is known to be characterized by …
