Ultracold atoms provide exciting opportunities in precision measurements using atom interferometers, quantum information and testing fundamental physics. Grating magneto-optical traps (gMOTs) in conjunction with atom chips provide an efficient and compact source of cold atoms. However, experimentally tuning the gMOT parameters for trapping maximum number of atoms is rather challenging, given the laborious installation of several microfabricated test gratings and re-establishing the ultra-high vacuum required for trapping.
In this poster, I will present a computational simulation of atom dynamics emerging from atom-light interactions, as well as gMOT parameter optimization for atom cooling and trapping. This is useful for quick analysis of various design techniques for gMOTs and atom chips.
