Coherent molecular bound states of bosons and fermions near a Feshbach resonance
arXiv:cond-mat/0404429 · doi:10.1103/PhysRevA.70.033609
Abstract
We analyze molecular bound states of atomic quantum gases near a Feshbach resonance. A simple, renormalizable field theoretic model is shown to have exact solutions in the two-body sector, whose binding energy agrees well with observed experimental results in both Bosonic and Fermionic cases. These solutions, which interpolate between BEC and BCS theories, also provide a more general variational ansatz for resonant superfluidity and related problems.
