Outline of Final Research Achievements

We have investigated the alkali atoms and Sr atoms in a hybrid-optical dipole-trap. For optical trapping, we have developed laser sources for 689 nm laser cooling, and have succeeded in a magneto-optical trapping of Sr using cooling lights with a wavelength of 689 nm. Moreover, we have succeeded in increasing the laser intensities and a spectroscopy of meta stable state in Sr.
We have studied a method to measure a nuclear anapole moment using alkali atoms in an optical-dipole trap, and to cancel a magnetic fluctuation. Furthermore, we have studied light shifts induced by parity nonconservation effect in an optical-dipole trap. Our results enable us to measure the light shifts in TeV scale.
We have investigated a method to suppress effects in 10 to -17 level using rotational and vibrational transitions in ultracold CaH, N2+, and O2+ molecules.
