Abstract
We report the results of our ab initio relativistic many-body calculations of the electric dipole moment (EDM) arising from the electron-nucleus tensor-pseudotensor (T-PT) interaction, the interaction of the nuclear Schiff moment (NSM) with the atomic electrons and the electric dipole polarizability for . Our relativistic random-phase approximation results are substantially larger than those of lower-order relativistic many-body perturbation theory and the results based on the relativistic coupled-cluster method with single and double excitations are highly accurate for all three properties that we have considered. We obtain from T-PT interaction, from NSM interaction, and . The former two results in combination with the measured value of EDM, when it becomes available, could yield the best limits for the T-PT coupling constant, EDMs, and chromo-EDMs of quarks and parameter, and would thereby shed light on leptoquark and supersymmetric models that predict violation.
