We review the current status of the study of parity and time invariance violation in atoms, nuclei and molecules. We focus on parity nonconservation (PNC) in cesium (CS) and three of the most promising areas of research: (i) PNC in a chain of isotopes, (ii) search for nuclear anapole moments, and (iii) search for permanent electric dipole moments (EDMs) of atoms and molecules, which in turn are caused by either an electron EDM or nuclear T, P-odd moments such as a nuclear EDM or nuclear Schiff moment.

The electric dipole moment of an electron (EDME) is investigated in the supersymmetric extra U(1) models. Neutralino sector is generally extended in these models and the neutralino contribution will then be important for the analysis of the EDME. Kinetic term mixings of Abelian gauginos are taken into account in our analysis. Numerical results for the extra U(1) models show that the EDME can be affected by the extra U(1) in a certain range of soft supersymmetry breaking parameters even if the extra U(1) gauge boson is heavy. The EDME may be a clue to find an extended gauge structure in the supersymmetric models.

In the context of the minimal supersymmetric seesaw model, the CP-violating neutrino Yukawa couplings might induce an electron electric dipole moment (EDM). The same interactions may also be responsible for the generation of the observed baryon asymmetry of the universe via leptogenesis. In the framework of mSUGRA, we identify in a model-independent way those patterns within the seesaw models which predict, barring unnatural cancelations, an electron EDM at a level probed by planned laboratory experiments and show that negative searches on τ→eγ decay may provide the strongest upper bound on the electron EDM. We also conclude that a possible future detection of the electron EDM is incompatible with thermal leptogenesis, even when flavor effects are accounted for.

Measurements of the electric dipole moment (EDM) of the neutron and the electron put the most stringent constraints on new sources of CP violation. CP violation is essential for generating the observed baryon asymmetry of the universe (BAU). Many models which propose large CP-odd mechanisms for BAU predict EDMs that exceed the limits of the most sensitive measurements. We are conducting a high sensitivity search for the electron EDM using a solid state system. It promises orders of magnitude improvement over atomic beam experiments solely from the available electron density. We present the experimental design and report on the current status.
