Outline

It has turned out during the last two decades that a large number of strongly interacting electrons in solids exhibit various emergent properties/functions, such as high-Tc superconductivity, colossal magnetoresistance, multiferroics, and quantum spin Hall effect, which cannot be understood within the framework of conventional semiconductor/metal physics. Our group aims at obtaining unprecedented and innovative electronic properties/functions, such as highly efficient energy conversion and dissipationless control of quantum state (information), by fully exploiting the complex interplay among multiple degrees of freedom of strongly correlated electrons, as well as the non-local and sensitive responses of relativistic electrons in a well-designed space-time structure.
