Query: Impact of overlapping resonances on magnetoassociation of cold molecules
  in tight traps   Overlapping Feshbach resonances are commonly observed in experiments with
ultracold atoms and can influence the molecule production process. We derive an
effective approach to describe magnetoassociation in an external trap in the
presence of multiple overlapping resonances. We study how the strength and
shape of the trap affects the energy level structure and demonstrate the
existence of a regime in which the conventional two-channel Landau-Zener
description of the molecule production process breaks down.
