Toward cold atom mixture of lithium and caesium — •Pierre Jouve — University of Nottingham, United Kingdom

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. These species are appealing because they offer favourable interactions properties and can be manipulated independently of each other due to their different resonance frequencies. Here we present the current status of our experiment. We detail the cooling schemes for the two atomic species and include the development and optimal loading of an optical dipole trap. We have constructed a two-species Zeeman slower for subsequent loading of lithium and caesium. We are also investigating ways to couple cold and ultracold caesium atoms to photons delivered through a waveguide. In principle such a light-matter interface can act as a building block for photon storage, optical switching or quantum computational tasks [1]. This work is funded by an EU-FET- young explorers project and includes researchers from the University of Vienna, Dresden, Jena and Nottingham.
