Towards Ultracold Mixtures on an Atom Chip — •Jonathan Nute, Matthew Jones, Asaf Paris Mandoki, Sonali Warriar, Peter Krüger, and Lucia Hackermüller — University of Nottingham, UK

Ultracold mixtures hold the promise of understanding new phases of matter and collisions at very low energies. We are setting up an experiment for bose-fermi mixtures of lithium and caesium, which are especially well suited to study impurities, transport, solitons or mixtures in optical lattices. We plan to introduce a micro-chip, which in conjunction with optical dipole trapping, will make it possible to trap these mixtures in low dimensions and tune their scattering lengths via Feshbach resonances. In this way it will also be possible to realise experiments with additional magnetic potentials, position dependent interactions or impurity dynamics. Here we present the current status of our experiment. We detail the cooling schemes for the two atom species and include the recent development of implementing an optical dipole trap. We discuss plans for introducing a glass cell to our caesium setup in preparation for our contribution to the Quantum Integrated Light and Matter Interface (QuILMI) European collaboration.
