The nature of Feshbach molecules in Bose-Einstein condensates
arXiv:cond-mat/0302082 · doi:10.1103/PhysRevLett.91.230401
Abstract
We discuss the long range nature of the molecules produced in recent experiments on molecular Bose-Einstein condensation. The properties of these molecules depend on the full two-body Hamiltonian and not just on the states of the system in the absence of interchannel couplings. The very long range nature of the state is crucial to the efficiency of production in the experiments. Our many-body treatment of the gas accounts for the full binary physics and describes properly how these molecular condensates can be directly probed.
