Research Subject
Design of novel strongly correlated oxides via ionic manipulation

研究の背景 Background


In the strongly correlated oxides, the strong correlations between different degrees of freedom (charge, spin, orbitals, etc.) often lead to the discoveries of emergent quantum phenomena such as superconductivity, magnetism and etc. Among these interactions, the electron-ion interaction is fairly strong, so the ionic manipulation would naturally give dramatic influence on the material properties. Thus, ionic manipulation in strongly correlated system based on physics and chemistry methods has become one of the most interesting topics in materials science with enormous practical applications.

研究の目標 Outcome


By maximizing ion manipulation and integrating known methods and theoretical models, we aim to freely and rationally control structures and physical properties of strongly correlated oxides. Our research is expected to lead to the acquisition of new knowledge and the development of unexplored fields in material science and applications. The obtained novel materials and theoretical models will contribute greatly not only to fundamental researches, but also to society and industry.
