Cross-Correlated Materials Research Group (CMRG)

It is well-known that the magnetization is induced by a magnetic field and the polarization by an electric field. In sharp contrast to these trivial cases, cross correlation means the off-diagonal responses between magnetization and electric field, for example. This effect is realized in the strongly correlated systems, where the various degrees of freedom of electrons, i.e., charge, spin, and orbital, are entangled by the many-body effects. These strongly correlated electronic systems show the rapid phase changes among solid-liquid-liquid crystal associated with the drastic changes of magnetic, electrical, and optical properties. We will design the novel cross-correlation functionalities in these many-body electron systems exploring new materials to create the new device concepts.
