Two-dimensional imbalanced Fermi gas in antiparallel magnetic fields

Abstract: We study a two-dimensional Fermi gas with an attractive interaction subjected to synthetic magnetic fields, which are assumed to be mutually antiparallel for two different spin components with population imbalance. By employing the mean-field approximation, we show that the Fulde-Ferrell state is energetically favored over the Larkin-Ovchinnikov state in the weak-coupling limit. We then elucidate the zero-temperature phase diagram in the space of attraction and two chemical potentials analytically at weak coup… Show more

“…In the Q ↓ = −Q ↑ case of oppositely charged components the homogeneous superfluid state with κ = 0 is favored. Said another way, the equally charged Fermi gas in an anti-parallel magnetic field requires a population imbalance for FFLO states as was recently studied in two-dimensions [45].…”
