    "abstract": "We compare the dynamics of a Bose-Einstein condensate in two coupled\npotential wells with atoms diffracting from a standing light wave. The\ncorresponding Hamiltonians have an identical appearance, but with a different\nset of commutation rules. Well-known diffraction phenomena as Pendellosung\noscillations between opposite momenta in the case of Bragg diffraction, and\nadiabatic transitions between momentum states are shown to have analogies in\nthe two-well case. They represent the collective exchange of a fixed number of\natoms between the wells.",
