Evaporative-cooling dynamics and stability of a continuous Bose-Einstein-condensate source
We present evaporative cooling simulations based on the direct simulation Monte Carlo method. Our system is a 54-cm-long atom guide with reflective barriers at the beginning and the end. The atom guide is continuously loaded with thermal atoms at the beginning. We show that it is critical to control the gravity component in the guiding direction to sustain a high classical phase-space density at the end of the atom guide. Transient oscillations are observed under certain conditions.
