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

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2007 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 31867626

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.
