Strong-Correlation Hybrid Materials Research Team
Team Leader
Yoshihiro IWASA (D.Eng.)
The purpose of this team is to find novel properties and functions of heterointerfaces of strongly correlated electron systems, in which many degrees of freedom interplay with each other and consequently yields variety of quantum phases.To electric field control of these competing phases could produce gigantic responses, which may be useful for contructing new electronics concepts, which we call Mottronics. We focus on the large electric filed produced at solid-liquid interfaces, and use this field to manipulate the quantum phasses in the strongly correlated electron systems. We aim at electric-field control of superconductivity, ferromagnetism, spin currents.
