Towards a Dual-Species Bose-Einstein Condensate of $^{7}$Li and $^{133}$Cs

Quantum degenerate mixtures of atomic gases are the subject of intensive study. Intriguing quantum phenomena flourish because of the extra complexity brought in by a second species. Being able to create a dual-species Bose-Einstein condensate is crucial to study these quantum effects. Here, we present technical progress towards creating a dual-species BEC of $^{7}$Li and $^{133}$Cs. The combination of heavy and light can open up new possibilities to probe and simulate disordered many-body systems.
