Query: Estimation of phase diffusion rates in a condensate interferometer using
  the Gross-Pitaevskii Equation   Atom interferometers using Bose-Einstein condensates are fundamentally
limited by a phase diffusion process that arises from atomic interactions. The
Gross-Pitaevskii equation is here used to accurately calculate the diffusion
rate for a Bragg interferometer. It is seen to agree with a Thomas-Fermi
approximation at large atom numbers and a perturbative approximation at low
atom numbers. The diffusion times obtained are generally longer than the
coherence times observed in experiments to date.
