Abstract
We have been studying laser-cooled and trapped atoms towards the detection of the permanent electric dipole moment (p-EDM). The existence of the p-EDM shows the CP-violation and its detection has significant implications for the test of the proposed elementary particle models. However, the current experimental accuracy has not yet reached the range of the predicted value of the standard model. Especially, a measurement error due to a shot noise is one of the important factors. To overcome the shot-noise limit, we are now trying to generate the atomic squeezed spin state.
