A fundamental limit for integrated atom optics with Bose-Einstein condensates
arXiv:cond-mat/0304199 · doi:10.1103/PhysRevA.68.023605
Abstract
The dynamical response of an atomic Bose-Einstein condensate manipulated by an integrated atom optics device such as a microtrap or a microfabricated waveguide is studied. We show that when the miniaturization of the device enforces a sufficiently high condensate density, three-body interactions lead to a spatial modulational instability that results in a fundamental limit on the coherent manipulation of Bose-Einstein condensates.
