Elastically-tunable electronic orders in correlated electron systems under a.c. uniaxial pressures (A13*)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 422213477

The project will utilize the novel capability to apply a.c. strains and stresses to experimentally determine various thermodynamic response functions of selected correlated electron systems under controlled uniaxial pressure. The project aims to accomplish the following scientific goals: (i) precise control of the triangular-lattice geometry of organic charge-transfer salts to study the interplay of charge, magnetic and lattice degrees of freedom under varying degrees of geometrical frustration; and (ii) search for the proposed phenomenon of viscoelasticity, i.e., low-frequency lattice dynamics, in correlated materials with critical elasticity.
