Spin in Funndamental Physics

Precision measurements at low energy are sensitive to phenomena on the same or even higher-energy scales as high-energy accelerator experiments. Especially studies of symmetry breaking are good probes of physics beyond the standard model of particles, such as the supersymmetry model. For example, searches for electric dipole moments of various particles, nuclei, atoms, and molecules limits the CP symmetry violation induced by new physics models. There are also experiments that search for time-reversal symmetry violation in nuclear reactions and beta decay using polarized nuclei. Spin is a key in all these experiments, and spin control continues to be developed. This talk will review the experiments with spin for fundamental physics and future prospects.
