Quantum-state controlled chemical reactions of ultracold potassium-rubidium molecules.
How does a chemical reaction proceed at ultralow temperatures? Can simple quantum mechanical rules such as quantum statistics, single partial-wave scattering, and quantum threshold laws provide a clear understanding of the molecular reactivity under a vanishing collision energy? Starting with an optically trapped near-quantum-degenerate gas of polar 40K87Rb molecules prepared in their absolute ...
متن کاملChemical pathways in ultracold reactions of SrF molecules
We present a theoretical investigation of the chemical reaction SrF + SrF → products, focusing on reactions at ultralow temperatures. We find that bond swapping SrF + SrF → Sr2 + F2 is energetically forbidden at these temperatures. Rather, the only energetically allowed reaction is SrF + SrF → SrF2 + Sr, and even then only singlet states of the SrF2 trimer can form. A calculation along a reduce...

متن کاملUltracold triplet molecules in the rovibrational ground state.
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 sizeab...
متن کاملProduction of ultracold ground-state LiRb molecules by photoassociation through a resonantly coupled state
We report on a resonantly coupled 2(1)-4(1) photoassociation resonance in LiRb. This pair of states displays interesting decay physics that hint at interference-like effects caused by two different decay paths. We observe decay to predominantly X 1 + v = 43, with significant numbers of molecules produced in X 1 + v = 2−12. This photoassociation resonance also produces ∼300 X 1 + v = 0 J = 0 mol...
