AB - Motivated by the ideas of using cold alkaline-earth atoms trapped in an optical lattice for realization of
optical atomic clocks, we investigate theoretically the perturbative effects of atom-atom interactions on a clock
transition frequency. These interactions are mediated by the dipole fields associated with the optically excited
atoms. We predict resonancelike features in the frequency shifts when constructive interference among atomic
dipoles occur. We theoretically demonstrate that by fine tuning the coherent dipole-dipole couplings in appropriately
designed lattice geometries, the undesirable frequency shifts can be greatly suppressed.
