Relativistic many-body aspects of the electron electric dipole moment searches using molecules

Abstract

The existence of an intrinsic electric dipole moment for the electron (eEDM), which is a consequence of simultaneous violations of parity and time reversal symmetries, is a very important problem in physics. This is because it can test theories beyond the Standard Model and provide insights into the matterantimatter asymmetry in the universe. The eEDM is determined by combining the measured shift in the energy of an atom or a molecule and the effective electric field, which can be calculated. This article deals with the calculations of effective electric fields in the leading molecular candidates in the search for eEDM, using ab initio relativistic quantum chemical methods.
