Query: Disordered Bose-Einstein Condensates in Quasi One-Dimensional Magnetic
  Microtraps   We analyze effects of a random magnetic potential in a microfabricated
waveguide for ultra-cold atoms. We find that the shape and position
fluctuations of a current carrying wire induce strongly disordered potential
that is quasiperiodic with a lengthscale set by the atom-wire separation. The
theory is used to explain quantitatively the experimentally observed
fragmentation of the quasi one-dimensional Bose-Einstein condensates.
Furthermore, we show that nonlinear dynamics can be used to provide important
insights into the nature of the strongly fragmented condensates. We argue that
a quantum phase transition from the superfluid to the insulating Bose glass
phase may be reached and detected under the realistic experimental conditions.
