Simulation of an atomic beam under magneto-optical influence — •Andreas Christian Wieltsch, Jan Haack, Stefan Schmidt, Marcel Willig, and Randolf Pohl — Johannes Gutenberg-Universität Mainz, QUANTUM, Institut für Physik & Exzellenzcluster PRISMA⁺, Mainz, Germany

We are developing a simulation software to track the movement of atoms in a laser spectroscopy experiment. In such an experiment atoms are slowed down under magneto-optical influence. The simulation can be used for evaluating different designs of the magnetic field in the slower or optimizing positions and diameters of apertures. This software is build for the Lithium experiment at the University of Mainz.

One way to model the light-atom interaction is using rate equations which are widely used for simulating the movement of atoms in such an experiment. The problem can also be described by the Optical Bloch equations, a set of differential equations describing the transitions between the energy states more precisely. We will present the generic implementation of the simulation program using both approaches, show results of the simulation and compare both methods. Due to the generic implementation, parts of the simulation software can also be used in e.g. the T-REX experiment.
