This review covers three different topics:
1. Measurements of Cs weak charge by C. Wieman group allowed to test the Standard Model predictions. We performed calculations of parity violation in Cs (also for other atoms of experimental interest like Tl, Fr, Ra+, Ba+) including all-orders summation of dominating diagrams in many-body theory and strong Coulomb field radiative corrections. The theoretical error was reduced two times. Conclusions for the Standard Model and possible ”new physics” will be discussed.
2. Atomic and molecular experiments can also be used to detect nuclear anapole moment - magnetic multipole which violates fundamental symmetries: parity (P) and charge conjugation (C).
3. Measurements of atomic and molecular electric dipole moments (EDM) present a possibility to search for physics beyond the Standard model. We explain different mechanisms generating atomic EDM, screening theorems for neutral atoms, ions and molecules, and present results of recent measurements testing models of CP violation. New generation of experiments with enhanced effects will put popular models (e.g. supersymmetry) to crucial test.
