The electric dipole moment of atomic {sup 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 {sup 199}Hg electric dipole moment, provide new bounds on the T reversal or CP violation parameters theta{sub QCD}, the tensor-pseudotensor coupling constant C{sub T}, and (d-tilde{sub u}-d-tilde{sub 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.
