Abstract
We consider fermionic polar molecules in a bilayer geometry where they are oriented perpendicularly to the layers, which permits both low inelastic losses and superfluid pairing. The dipole-dipole interaction between molecules of different layers leads to the emergence of interlayer superfluids. The superfluid regimes range from BCS-like fermionic superfluidity with a high to Bose-Einstein (quasi-)condensation of interlayer dimers, thus exhibiting a peculiar BCS–Bose-Einstein condensation crossover. We show that one can cover the entire crossover regime under current experimental conditions.
