Abstract
We theoretically investigate Raman photoassociation of a degenerate
Bose-Fermi mixture of atoms and the subsequent prospect for anomalous (Cooper)
pairing between atoms and molecules. Stable fermionic molecules are created via
free-bound-bound stimulated Raman adiabatic passage which, in contrast to
purely bosonic systems, can occur in spite of collisions. With the leftover
atomic condensate to enhance intrafermion interactions, the superfluid
transition to atom-molecule Cooper pairs occurs at a temperature that is
roughly an order of magnitude below what is currently feasible.
