Quantum fluid in bilayers of ultra-cold polar Fermi molecules — Michael Klawunn, •Alexander Pikovski, and Luis Santos — Institut für Theoretische Physik, Leibniz Universität Hannover, Appelstr. 2, 30167 Hannover, Germany

Quantum degenerate cold molecules with a strong electric dipole moment may soon be within experimental reach. We study a system of ultracold polar Fermi molecules confined into two neighboring layers, e.g. in a two-well potential. The main interaction between these layers is provided by the dipole-dipole forces (all dipoles are polarized in one direction). It is found that in the quantum degenerate regime, the interaction may lead to the formation of Cooper-like pairs, where a molecule in layer 1 is paired with a molecule in layer 2. We discuss the appearance of this paired state and give an outlook to future work.
