Dissipative effects in a cloud of ultracold atoms — •Ralf Labouvie, Andreas Vogler, Felix Stubenrauch, Vera Guarrera, Giovanni Barontini, and Herwig Ott — TU Kaiserslautern, Deutschland

This talk addresses the experimental investigation of dissipative effects in a cloud of ultracold atoms.

In our experiment, we use a focussed electron-beam to locally remove atoms from the system. The possibility to modify the electron-beam current and width allows us to control the strength of the dissipation. We investigate the behaviour of the quantum system under different dissipative conditions and temperatures.
