| Outline of Final Research Achievements |
In this work, we clarified electronic dynamics after photoexcitation in correlated systems, Mott insulators and organic charge transfer complexes, by performing pump-probe spectroscopy with a high time resolution by using an ultrafast pulse generated from a self-produced noncolinear optical parametric amplifier. Especially, we succeeded in real-time observation of charge-spin dynamics such as generation of magnetic polarons and coherent oscillations related with two-magnon excitations.
