Phys. Rev. A 66, 043418 (2002) [11 pages]Coherent pulse output from Bose-Einstein condensates in Wannier-Stark systemsReceived 28 May 2002; revised 22 August 2002; published 25 October 2002 The pulsed output from a Bose-Einstein condensate can be described using ordinary one-particle quantum mechanics. The initial state is described in terms of Stark resonances truncated in momentum space. The states obtained in this way resemble the normalizable scattering states defined in terms of Moshinsky functions. The validity of this approach and the influence of the initial population on the pulse formation is discussed. Finally, we describe an experimental setup to manufacture and observe pulsed output in Wannier-Stark systems. © 2002 The American Physical Society URL:
