11. The prospect of Cooper-pairing induced by BEC mediated interactions was treated by H. Heiselberg, Phys. Rev. Lett. PRLTAO 0031-9007 10.1103/PhysRevLett. 85.2418 85, 2418 (2000).
12. If the attractive Yukawa interaction that follows from the static perturbation treatment [see, for instance, M. J. Bijlsma, B. A. Heringa, and H. T. C. Stoof, Phys. Rev. A PLRAAN 1050-2947 10.1103/PhysRevA.61.053601 61, 053601 (2000)]
13. is valid then the formation of Cooper pairs that are smaller than the Yukawa range is similar to that of excitons in exciton BECs, see, for instance, P. Nozieres and D. Saint James, J. Phys. (Paris) JOPQAG 0302-0738 43, 1133 (1982). Magnetic instabilities of spinor BECs or phase separation of a BEC-mixture can provide a quantum phase transition in cold atom fermion-BEC mixtures.
14. Cold atom single component fermion-BEC mixtures with a Fermi velocity vF that exceeds the BEC sound velocity c, exhibit zero-sound as well as BEC-sound collective excitations, whereas vF
