We perform accurate calculations of the dependence of transition frequencies in two valence electron atoms and ions on a variation of the fine structure constant, alpha. The relativistic Hartree-Fock method is used with many-body perturbation theory and configuration interaction methods to calculate transition frequencies. The results are to be used in atomic-clock-type laboratory experiments designed to test whether alpha varies in time.

Long-baseline atom interferometers could detect ultra-light spin-2 dark matter through three coupling channels, reaching mass and coupling ranges that LIGO and LISA cannot cover.
