Biography
The main research subject of our laboratory is theoretical study of quantum transport in nano-scale devices based on various methods. This research subject, which is also called ‘mesoscopic physics’, has been studied for long time by focusing on quantum mechanical nature of electrons. Recently, mesoscopic systems are studied from novel viewpoints such as nonequilibrium many-body phenomena, shot noise, high-speed drive phenomena, spintronics, and so on. In order to explain these phenomena, we are constructing theories by utilizing nonequilibrium statistical mechanics, fundamental theory of quantum mechanics, and many-body physics. Examples of our recent activities are nonequilibruim transport properties of the Kondo quantum dots, electron and heat transport under time-dependent external fields, and many-body effect in thermal transport of phonons.
