Spectroscopy of the soliton lattice formation in quasi-one-dimensional fermionic superfluids with population imbalance
Motivated by recent experiments in low-dimensional trapped fermionic superfluids, we study a quasi-one-dimensional (quasi-1D) superfluid with a population imbalance between two hyperfine states using an exact mean-field solution for the order parameter. When an effective ``magnetic field'' exceeds a critical value, the superfluid order parameter develops spatial inhomogeneity in the …
