By using organic charge-transfer salts, having model character for strongly correlated electrons, the following fundamental aspects will be explored: (1) The universal properties of the Mott transition, (2) the effects of charge degrees of freedom in systems on the insulating side of the Mott transition; (3) various spin-liquid ground states and instabilities in strongly frustrated quasi-2D Mott insulators, and (4) the unusual metal-insulator transition in k-(BEDT-TTF)2Hg(SCN)2Cl.

利用具有强关联电子模型性质的有机电荷转移盐，我们将探索以下基本方面：(1)Mott转变的普遍性质；(2)体系中电荷自由度对Mott转变绝缘侧的影响；(3)强受挫的准2D Mott绝缘体中各种自旋-液体基态和不稳定性；(4)k-(BEDT-TTf)2HG(SCN)2Cl中反常的金属-绝缘体转变。
