STRONGLY CORRELATED ELECTRON SYSTEMS: FERTILE GROUND FOR DEVELOPMENT OF NEW FUNCTIONAL MATERIALS
The semiconductor technology is the most significant accomplishment originating from twenty-century solid state physics. The band model well describes the charge carriers in semiconductors, and is very useful for designing many kinds of devices such as diodes, transistors, memories, photodiodes, and CCDs. Nonetheless, the physical properties of all the materials cannot be predicted by the band model. Strong correlation between electrons is a major source of the discrepancy with the band model. A lot of issues related to the strong electron correlation still remain to be solved and hence attract a bunch of researchers. Another reason why we are interested in The strongly correlated electron systems also provide a rich variety of functions. We are exploring novel physical properties arising from strong electron correlation by paying special attention to symmetry breaking.
