Query: Dynamics of double-well Bose-Einstein Condensates subject to external
  Gaussian white noise   Dynamical properties of the Bose-Einstein condensate in double-well potential
subject to Gaussian white noise are investigated by numerically solving the
time-dependent Gross-Pitaevskii equation. The Gaussian white noise is used to
describe influence of the random environmental disturbance on the double-well
condensate. Dynamical evolutions from three different initial states, the
Josephson oscillation state, the running phase and $\pi$-mode macroscopic
quantum self-trapping states are considered. It is shown that the system is
rather robust with respect to the weak noise whose strength is small and change
rate is high. If the evolution time is sufficiently long, the weak noise will
finally drive the system to evolve from high energy states to low energy
states, but in a manner rather different from the energy-dissipation effect. In
presence of strong noise with either large strength or slow change rate, the
double-well condensate may exhibit very irregular dynamical behaviors.
