Query: Cold interactions between an Yb$^+$ ion and a Li atom: Prospects for
  sympathetic cooling, radiative association, and Feshbach resonances   The electronic structure of the (LiYb)$^+$ molecular ion is investigated with
two variants of the coupled cluster method restricted to single, double, and
noniterative or linear triple excitations. Potential energy curves for the
ground and excited states, permanent and transition electric dipole movements,
and long-range interaction coefficients $C_4$ and $C_6$ are reported. The data
is subsequently employed in scattering calculations and photoassociation
studies. Feshbach resonances are shown to be measurable despite the ion's
micromotion in the Paul trap. Molecular ions can be formed in their singlet
electronic ground state by one-photon photoassociation and in triplet states by
two-photon photoassociation; and control of cold atom-ion chemistry based on
Feshbach resonances should be feasible. Conditions for sympathetic cooling of
an Yb$^+$ ion by an ultracold gas of Li atoms are found to be favorable in the
temperature range of 10$\,$mK to 10$\,$nK; and further improvements using
Feshbach resonances should be possible. Overall, these results suggest
excellent prospects for building a quantum simulator with ultracold Yb$^+$ ions
and Li atoms.
