A tunable quantum gas for the study of universal time dynamics far from equilibrium — •Maurus Hans, Celia Viermann, Helmut Strobel, and Markus K. Oberthaler — Kirchhoff-Institut für Physik, Universität Heidelberg, Deutschland
Degenerate quantum gases offer a particularly isolated setting to study the relaxation of quantum many-body systems initialised far from equilibrium. For many scenarios it is desirable to control the atomic interactions over a wide range. For this, a 39K Bose-Einstein condensate is a promising experimental system as it exhibits broad magnetic Feshbach resonances for the tuning of the scattering length.
We give an overview of our experimental setup including the implementation of gray molasses sub-Doppler cooling and all-optical evaporation to Bose-Einstein condensation. Furthermore, we present first observations of far from equilibrium dynamics.
