To explore the mechanism responsible for the generation of observed matter-antimatter asymmetry in the Universe, the experimental study on the violation of the fundamental symmetry using the laser cooled and trapped atoms is being promoted. One such phenomenon of our interest is the intrinsic electric dipole moment (EDM) of either elementary or composite systems. The non-zero observation of...

A permanent electric dipole moment (EDM) of a particle or system would arise due to breaking of time-reversal (T), or equivalently charge-conjugation/parity (CP) symmetry. Over the past five decades, a number of experiments on the neutron, atoms and molecules have only set upper limits on EDMs, and the search continues, motivated in large part by the expectation that beyond Standard-Model...

It is well known that the existence of a permanent electric dipole moment (EDM) of a fundamental particle such as the neutron or electron violates both parity and time reversal symmetries. Many theories of physics beyond the standard model predict EDMs which should be observable by a new generation of experiments. For the electron, this new generation almost entirely involves measurements...

The most precise measurement of the properties of an elementary particle is the magnetic dipole of the electron which we have been able to measure to 3 parts in 10^13. Perhaps the greatest triumph of the Standard Model of particle physics is a prediction of the measured value to nearly this precision. The electron's electric dipole moment provides an important constraint on extensions to...

Since the electric dipole moment (EDM) in diamagnetic atoms strongly depends on nuclear structure, the EDM searches for various species are meaningful. We aim to measure the EDM in $^{129}$Xe to a size of 10$^{-28}$ $e$cm, stepping into a domain below the present upper limit by one order of magnitude. Such the EDM search requires an improvement in the frequency precision down to 1 nHz. In this...
