Coherent quantum oscillations in coupled traps with ultracold atoms

Contact: N.M.Bogoliubov

The dynamics of two traps with ultracold atoms and connected 
by Josephson type coupling, is shown to exhibit a transition from dispersive
dynamics to localized coherent oscillations. This transition is controlled 
by coupling strength and energy offset between the traps. The dynamics is also
shown to be exactly that of a Heisenberg chain with a linear magnetic field.
Possible applications for ``quantum-state engineering'' are discussed.
