Research Abstract |
To explore novel electronic phases with charge and spin fluctuations, we studied triangular-lattice organics situated near Mott transition. We found that the Mott transition is accompanied with unconventional criticality as found in both of charge and spin degrees of freedom. Moreover, it is revealed that spin frustration determines the ground state in Mott insulating phase, and presence or absence of pseudo-gap, superconducting critical temperature and strong or weak Mott transition.
