Long-Range Nature of Feshbach Molecules in Bose-Einstein Condensates



T K hler, T Gasenzer, Paul S. Julienne, K Burnett


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 nature of the state is crucial to the efficiency of production in the experiments. Models that do not embed the full binary physics into the many-body treatment will fail to properly describe how these molecular condensates can be directly probed.
