Towards ultracold mixtures of lithium and caesium — •Elisa Da Ros, Pierre Jouve, Jonathan Nute, Jizhou Wu, Nathan Cooper, and Lucia Hackermüller — University of Nottingham, United Kingdom

Ultracold mixtures hold the promise of understanding new phases of matter and collisions at very low energies. We showcase here our experiment capable of producing ultracold clouds of both bosonic caesium-133 and fermionic lithium-6 using a crossed-beam optical dipole trap.

We present the results of in situ optical density measurements of molecular lithium-6 Bose-Einstein condensates, aiming to compare different theoretical models. We also explain the design, construction and characterization of a dual species effusive oven for fast loading of magneto-optical traps integral to our experiments involving ultracold mixtures of both species. Finally, we exhibit our progress towards a quantum integrated light and matter interface (QuILMI) using waveguide chips in collaboration with the University of Jena, University of Vienna and the Max Planck Institute for the Physics of Complex Systems.
