Spinor dynamics in Fock space — •Reinhold Walser, Lev Plimak, Carsten Weiß, and Wolfgang P. Schleich — Abteilung Quantenphysik, Universität Ulm, Germany

Well isolated trapped multi-component Bose gases represent an ideal environment to investigate exact many-body dynamics of simple spin systems [1-4]. In the present contribution, we will discuss static and dynamic aspects of quantum systems where only few quantized modes need to be considered. On one hand, the discrete nature of the Fock representation leads to highly efficient numerical algorithms, but on the other hand, it also leads to very intuitive description in terms of many-body potentials and effective masses.
