Studying the violation of parity and time-reversal invariance in atomic systems has proven to
be a very effective means of testing the electroweak theory at low energy and searching for …

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 …

We perform calculations of the CP-violating atomic and molecular electric dipole moments
(EDMs) induced by the interaction of the nuclear Schiff moments with electrons. EDMs of …

We report on a measurement of the CP-violating permanent electric dipole moment (EDM) of
the neutral Xe 129 atom. Our experimental approach is based on the detection of the free …

Nuclei with an octupole deformation have a nonzero electric octupole moment, electric
dipole moment (EDM), Schiff moment, and magnetic quadrupole moment (MQM) in the …

According to the Schiff theorem, a static nuclear electric dipole moment (EDM) does not
produce atomic and molecular EDMs. However, interaction with the axion dark matter field …

We show that existing calculations of the interaction between nuclear Schiff moments and
electrons in molecules use an inaccurate operator which gives rise to significant errors. By …

When an atom is placed into an oscillating electric field with frequency far from atomic
resonances, the atomic electrons partly shield this field at the nucleus. It is conjectured that …

According to the Schiff theorem, the atomic electrons completely screen the atomic nucleus
from an external static electric field. However, this is not the case if the field is time …

The electric dipole moments for the lowest 1/2+ states of Xe and Ba isotopes are calculated
in terms of the nuclear shell model, which includes two-body nucleon interactions violating …
