Abstract

We present results of our three experimental setups. For our molecular lithium BEC we study strongly interacting systems insitu and compare the profile and temperature to a semi-ideal description and to a full Hatree-Fock description. In addition we explore non-equilibrium effects in the Li-Li molecule creation. We also have built an atom-photon interface, by trapping cold Cs atoms in an intersection of an optical fibre. For this we laser drill a 30 µm through-hole orthogonal to the fibre and trap about 300 atoms in the interaction region. Trapping the atoms in the centre of the guided light mode allows excellent overlap of photons and atoms. In addition we simulate different hole-shapes in order to find optimum transmission. We show that with the addition of a cavity reaching the strong coupling regime should be possible. We will also report on our efforts to build small, compact and portable quantum systems
