Such molecules exhibit both a magnetic dipole moment and an electric dipole moment in their ground state. This extra degree of freedom opens up new avenues of research including the study of exotic states of matter, the shielding of molecular collisions and the simulation of lattice spin models. In detail, the thesis reports the first and only ultracold mixture of Cs and Yb in the world, giving details of the methods used to cool such contrasting atomic species together. Using sensitive two-colour photoassociation measurements to measure the binding energies of the near-threshold CsYb molecular levels in the electronic ground state has allowed the previously unknown scattering lengths to be accurately determined for all the Cs–Yb isotopic combinations. As part of this work, the one-photon photoassociation of ultracold Cs*Yb is also studied, yielding useful information on the excited-state potential. Knowledge of the scattering lengths enables a strategy to be devised to cool both species to quantum degeneracy and, crucially, determines the positions of interspecies Feshbach resonances required for efficient association of ground-state CsYb molecules. With these results, the prospect of bringing a new molecule into the ultracold regime has become considerably closer. .Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Phase transformations (Statistical physics)Condensed matterQuantum theorySpectrum analysisMicroscopyQuantum Gases and Condensateshttps://scigraph.springernature.com/ontologies/product-market-codes/P24033Quantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Spectroscopy and Microscopyhttps://scigraph.springernature.com/ontologies/product-market-codes/P31090Phase transformations (Statistical physics)Condensed matter.Quantum theory.Spectrum analysis.Microscopy.Quantum Gases and Condensates.Quantum Physics.Spectroscopy and Microscopy.536.56028539.7Guttridge Alexanderauthttp://id.loc.gov/vocabulary/relators/aut1061501BOOK9910337869103321Photoassociation of Ultracold CsYb Molecules and Determination of Interspecies Scattering Lengths2518964UNINA
