Towards a two-species quantum degenerate gas of ⁶Li and ¹³³Cs — •Rico Pires, Marc Repp, Kristina Meyer, Johannes Deiglmayr, and Matthias Weidemüller — Physikalisches Institut, Ruprecht-Karls Universität Heidelberg, Heidelberg, Germany

We present the design of the new experimental apparatus currently being built. The setup will allow the formation of clouds of ultracold Li and Cs atoms via standard laser cooling techniques. Successive loading into optical dipole traps and subsequent evaporative cooling enables us to achieve quantum degeneracy. From this starting point, two different routes can be taken. The ramping of Feshbach fields followed by stimulated Raman adiabatic passage (STIRAP) can be used to create deeply bound LiCs molecules. As these exhibit the largest dipole moment among all alkali atom combinations, they present a promising candidate for the observation of dipolar effects such as new quantum phases. On the other side, the ability to tune the interaction strength via the magnetic field, allows one to study few body effects in this ensemble.
