20.10.2015 - Markus Debatin - Dipolar molecules - molecular physics on pathway towards dipolar quantum gases

Ultracold heteronuclear molecules are a prime candidate for investigation of strongly-interacting dipolar quantum gases and ultracold chemistry. If high phase space density samples of ground state molecules are desired, assembling the molecules from laser-cooled atoms has proven to be a viable strategy. Focussing on LiK the creation of ultracold mixtures, the assembly of Feshbach molecules and possible pathways for stimulated Raman adiabatic passage (STIRAP) ground-state transfer will be explained and experimental spectroscopy results will be given. A comparison to the much heavier RbCs will be made in order to highlight peculiarities of the LiK molecule and the high potential of the method.
