Towards ultracold mixtures on an atom chip — •Sonali Warriar, Sebastian Nickel, Lucia Hackermüller, and Peter Krüger — University of Nottingham, Nottingham, United Kingdom

Ultracold mixtures hold the promise of understanding new phases of matter and collisions at very low energies. We are planning to set up experiments with Lithium and Cesium mixtures on a chip, i.e. ⁶Li - ⁷Li mixtures, heteronuclear LiCs or homonuclear ⁶Li₂ molecules. By combining the capabilities of the atom chip with optical dipole trapping, it would be possible to trap these mixtures in low dimensions and tune their scattering lengths via Feshbach resonances. With atom chips, it would also be possible to realise experiments with additional magnetic potentials or have cold atoms interacting with a 2D electron gas. Here we present the current status of our experiment. This includes the setup of our lithium laser system, i.e. absorption spectroscopy and tapered amplifier laser setup. An illustration of our planned experimental chamber is also given.
