Calculation of P,T-odd electric dipole moments for diamagnetic atoms 129Xe, 171Yb, 199Hg, 211Rn, and 225Ra
Abstract
Electric dipole moments of diamagnetic atoms of experimental interest are calculated using the relativistic Hartree-Fock and random-phase approximation methods, the many-body perturbation theory and configuration interaction technique. We consider P,T-odd interactions which give rise to atomic electric dipole moment in the second order of the perturbation theory. These include nuclear Schiff moment, P,T-odd electron-nucleon interaction and electron electric dipole moment. Interpretation of a new experimental constraint of a permanent electric dipole moment of 199Hg [W. C. Griffith et al., Phys. Rev. Lett. 102, 101601 (2009)] is discussed.
