Abstract: Bose-Einstein condensates in atomic gases form through the use of evaporative cooling techniques. Using these techniques, a relatively hot gas of interacting atoms is cooled below the critical point for condensation, at which quantum effects are expected to be important. In this talk, I will overview a technique for simulating the dynamics of this cooling process with quantum effects included. The simulated equations are similar to the Gross-Pitaevskii (Non-Linear Schroedinger) equation but contain stochastic terms. Three dimensional results can be obtained for small samples of weakly interacting atoms.
