%T Immersed Quantum Systems : A Sodium Bose-Einstein Condensate for Polaron Studies
%U https://archiv.ub.uni-heidelberg.de/volltextserver/10949/
%X The subject of this work is the setup of an experiment to study immersed quantum systems using bosonic 23Na and fermionic 6Li. Bose-Einstein condensation of 23Na has been achieved in two di erent magnetic trap con gurations, namely the plugged quadrupole trap and the cloverleaf trap. Both are compared with respect to their suitability for a two-species experiment using this particular isotopes. In such a mixture, it should be possible to investigate polarons, which are quasiparticles, emerging when one of components of the mixture has only a very rare concentration. Furthermore, a theoretical study of the polaron will be discussed. A mean- eld calculation has been carried out in order to simulate the impurity behavior in the presence of a large bosonic background gas.
