“Evaporative cooling of trapped gas particles: a numerical analysis”<\/p>\n
Senior Thesis presented by Ethan Emerson<\/p>\n
This thesis develops a numerical simulation of evaporative cooling of atomic vapor as it pertains to the ultracold (nanoKelvin) phenomenon of Bose-Einstein condensation. I simulate evaporative cooling by two methods: one using a simplified \u201cinstant\u201d equilibration process and a second using an elastic-collision equilibration. Both of these processes are analyzed for their validity, and subsequently used to analyze various routines for evaporative cooling. This is done by assessing the temperature and phase-space density data generated by the simulations. These programs provide an insight into optimal processes for achieving the ultracold temperatures and high phase-space densities necessary for BEC.<\/p>\n
