Main research subjects in this group are the experimental investigations on the novel electronic states emerging in the organic molecular materials. We are actively studying the interesting and important issues on the condensed matter physics from the viewpoint of the combination between the characteristic flexibility of the lattices and strongly correlated π-electrons in the organic materials.
Characteristic properties of the organic materials are multiple flexibilities owing to the assemble structure of nanometer-size molecules. This flexibility comes up recently for developing the organic electronic devices. We explore the fundamental electronic properties from the superconductivity to the insulating ground states resulting from the strongly correlated π-electrons. Such novel electronic states connect closely to the flexible and multiple degrees of freedom among charges, spins, and molecular lattices in the organic system.
