Collective phenomena in organic charge-transfer salts close to the Mott transition (B06)

利用具有强关联电子模型特征的有机电荷转移盐，将探讨下列基本问题：（1）Mott跃迁的普遍性质;（2）系统中电荷自由度对Mott跃迁绝缘侧的影响;（3）强阻挫准二维Mott绝缘体中的各种自旋液体基态和不稳定性;（4）k-（BEDT-TTF）_2Hg（SCN）_2Cl中不寻常的金属-绝缘体相变。

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.
