Coexistence of density wave and superfluid order in a dipolar Fermi gas
Coexistence of density wave and superfluid order in a dipolar Fermi gas
We analyze the coexistence of superfluid and density wave (stripe) order in a quasi-two-dimensional gas of dipolar fermions aligned by an external field. Remarkably, the anisotropic nature of the dipolar interaction allows for such a coexistence in a large region of the zero-temperature phase diagram. In this region, the repulsive …
