This thesis presents a setup capable of creating arbitrary potentials for a two-dimensional Bose-Einstein condensate. A Digital Micromirror Device is used to spatially modulate and thus shape a laser beam. Reimaged to the position of the atomic …
This thesis presents the design and implementation of a high resolution objective lens for imaging ultracold atomic clouds of sodium and lithium in the NaLi experiment. The lens has been developed using the ray tracing software OSLO. The design …
This thesis reports on the implementation of the Fröhlich Hamiltonian in an ultracold atomic mixture. To this end, impurity atoms are immersed into a macroscopic Bose-Einstein condensate (BEC). The impurities are tightly trapped in one direction by a …
