Description

In this presentation, the current status of a comagnetometer which is dedicated
to search for the permanent electric dipole moment of the electron (eEDM) using
francium atoms is discussed. The designed comagnetometer consists of laser-cooled
Rb-87 and Cs-133 atoms trapped simultaneously in an optical lattice in order to
observe the effects of Zeeman shift and vector light shift independently. This is
expected to increase the measurement precision of the eEDM, consequently allows
to search for the CP violation with high precision.
