Stable Topological Superfluid Phase of Ultracold Polar Fermionic Molecules
We show that single-component fermionic polar molecules confined to a 2D geometry and dressed by a microwave field may acquire an attractive $1/{r}^{3}$ dipole-dipole interaction leading to superfluid $p$-wave pairing at sufficiently low temperatures even in the BCS regime. The emerging state is the topological ${p}_{x}+i{p}_{y}$ phase promising for topologically …
