We perform two-photon photoassociation spectroscopy of the heteronuclear CsYb molecule to measure the binding energies of near-threshold vibrational levels of the $X{\phantom{\rule{3.33333pt}{0ex}}}^{2}{\mathrm{\ensuremath{\Sigma}}}_{1/2}^{+}$ molecular ground state. We report results for $^{133}\mathrm{Cs}^{170}\mathrm{Yb}$, $^{133}\mathrm{Cs}^{173}\mathrm{Yb}$, and $^{133}\mathrm{Cs}^{174}\mathrm{Yb}$, in each case determining the energy of several vibrational levels including the least-bound…

Magnetic Feshbach resonances between atoms in $^2$S and $^3$P$_0$ states: mechanisms and dependence on atomic properties

Magnetically tunable Feshbach resonances exist in ultracold collisions between atoms in 2 S and 3 P 0 states, such as an alkali-metal atom colliding with Yb or Sr in a clock state. We investigate the

Controlling the Scattering Length of Ultracold Dipolar Molecules.

It is found that molecules with B[over ˜]>10^{8} are immune to any quenching losses when a sufficient ac field is applied, the ratio elastic to quench processes can reach values above 10^{3}, and that the value and sign of the scattering length can be tuned.

With the one-photon photoassociation measurements complete, we now expand our binding energy measurements to the ground state. An accurate model of the electronic ground state potential is essential

Feshbach Resonances in p-Wave Three-Body Recombination within Fermi-Fermi Mixtures of Open-Shell 6Li and Closed-Shell 173Yb Atoms

A comparison of experimental and theoretical line shapes of the recombination process indicates that the characteristic asymmetric line shape as a function of applied magnetic field and a maximum recombination rate coefficient that is independent of temperature can only be explained by triatomic collisions with nonzero, p-wave total orbital angular momentum.
