Outline of Final Research Achievements |
We performed theoretical studies on nano-scale devices under fast driving: (1) We constructed a theory of current fluctuation under strong periodic external fields for quantum dots with Coulomb interaction. (2) We constructed a theory of spin-current fluctuation for spin-current generation at an interface between a ferromagnetic insulator and a metal due to spin Seebeck effect and spin pumping. (3) We constructed a theory of charge pumping in quantum dot systems under periodic modulation of reservoir parameters. (4) We studied heat transport via a nano-scale device theoretically. (5) We discussed fast magnetic response of a ferromagnetic insulator ErFeO3.
