Outline of Final Research Achievements

In this project, we aimed to develop spin noise spectroscopy for photochemical intermediates with a sensitivity to correlation with the electronic transition. We have constructed spin noise spectroscopy system with wavelength tunable pulse laser source, and successfully observed spin noise signal of conduction band electrons in GaAs. We further studied electronic excited state dynamics of organic solids embedded in an optical microcavity and found a marked modulation of the photoexcited state dynamics by the polariton formation.
