Description
Obtaining rigorous bounds on CP-violation at the fundamental level is complicated by the contributions of several subatomic sources to the net P,T-odd electric dipole moment (EDM) of atoms and molecules. Consequently, several experiments of complementary sensitivity to these individual sources are required. I will discuss a simply-applicable qualitative model for analyzing the effect of different atomic and molecular species in a global analysis of CP-violation. The focus will be on systems with closed-shell electronic shells, actinide molecules in high charge states and polyatomic molecules. We will compare phenomenological scaling laws with accurate density functional theory and coupled cluster calculations to analyze the influence of relativistic and chemical enhancements as well as electron correlation effects. In conclusion we will infer the most promising directions for EDM measurements from an electronic structure perspective.
