| Research Abstract |
The equilibrium state of electron-hole systems is an “epitome” of the condensed matter physics, providing an ultimate stage for the fundamental study on it. This system is also important from the viewpoint of application to the laser devices. We developed a novel method to properly deal with the many body effect of the low-dimensional electron-hole systems, and succeeded in clarifying their global phase diagrams. In addtion, we made focus on the Dirac electron systems, which interpolates the electron-hole systems (semimetals) and the semiconducting systems. The cyclrotron resonance on graphene under strong magnetic field and the biexcitons and trions in semiconducting carbon nanotubes are studied. We further studied the multiband Hubbard models (ex. multiorbital systems and Kagome lattices), which are the strongly correlated electron systems relevant to the electron-hole systems.
