Ultracold Triplet Molecules in the Rovibrational Ground State

Florian J. W. Lang, Klaus Winkler, Christoph Strauß +2 more

We report here on the production of an ultracold gas of tightly bound Rb2 triplet molecules in the rovibrational ground state, close to quantum degeneracy. This is achieved by optically transferring weakly bound Rb2 molecules to the absolute lowest level of the ground triplet potential with a transfer efficiency of about 90%. The transfer takes place in a 3D optical lattice which traps a sizeable fraction of the tightly bound molecules with a lifetime exceeding 200 ms.

A New Spin on Ultracold Molecules

We create fermionic dipolar 23 Na 6 Li molecules in their triplet ground state from an ultracold mixture of 23 Na and 6 Li.Using magnetoassociation across a narrow Feshbach resonance followed by a two-photon stimulated Raman adiabatic passage to the triplet ground state, we produce 3 × 10 4 ground state molecules in a spin-polarized state.We observe a lifetime of 4.6 s in an isolated molecular sample, approaching the p-wave universal rate limit.Electron spin resonance spectroscopy of the triplet state was used to determine the hyperfine structure of this previously unobserved molecular state.We create fermionic dipolar 23 Na 6 Li molecules in their triplet ground state from an ultracold mixture of 23 Na and 6 Li.Using magnetoassociation across a narrow Feshbach resonance followed by a two-photon stimulated Raman adiabatic passage to the triplet ground state, we produce 3 × 10 4 ground state molecules in a spin-polarized state.We observe a lifetime of 4.6 s in an isolated molecular sample, approaching the p-wave universal rate limit.Electron spin resonance spectroscopy of the triplet state was used to determine the hyperfine structure of this previously unobserved molecular state.
