    "Ultracold Dipolar Molecules of NaK"
    
    Quantum  gases  of  dipolar  molecules  hold promise  for  precision  measurements,  quantum information and the creation of novel many-body systems. In this talk I will report on our creation of an ultracold dipolar gas of fermionic 23Na40K molecules in their absolute rovibrational and hyperfine ground state. Starting from weakly bound Feshbach molecules, we perform hyperfine resolved two-photon transfer into the singlet X1Σ+|v=0,J=0⟩ ground state, coherently bridging a binding energy difference of 0.65 eV via stimulated rapid adiabatic passage. The spin-polarized, nearly quantum degenerate molecular gas displays lifetimes of several seconds. In recent studies, we demonstrated coherent control over the hyperfine and rotational degrees of freedom, and observed second-long spin coherence times. With these advances, the exploration of many-body physics with strongly dipolar molecules and quantum information applications are within reach.
