Abstract

The electric dipole moment of atomic ${}^{199}{Hg}$ induced by the nuclear Schiff moment and the tensor-pseudotensor electron-nucleus interactions are calculated. For this, we develop and employ a novel method based on the relativistic coupled-cluster theory. The results of our theoretical calculations, combined with the latest experimental result of the ${}^{199}{Hg}$ electric dipole moment, provide new bounds on the $T$ reversal or $C P$ violation parameters $θ_{QCD}$ , the tensor-pseudotensor coupling constant $C_{T}$ , and ( ${\tilde{d}}_{u} - {\tilde{d}}_{d}$ ). This is the most accurate calculation of these parameters to date. We highlight the crucial role of electron correlation effects in their interplay with the $P$ , $T$ violating interactions. Our results demonstrate substantial changes in the results of earlier calculations of these parameters which can be attributed to the more accurate inclusion of important correlation effects.
