Strong electron-lattice coupling in correlated intermetallic compounds near valence- and structural instabilities (A01+)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2020 to 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 422213477

The project A01 (Wolf/Lang) will study the close interlocking of electronic and lattice degrees of freedom upon pressure-tuning systems into the vicinity of phase transitions. Special attention will be devoted to the expected occurrence of critical elasticity around the valence transition in EuPd2Si2 and related variants. A second focus will be the possibility to induce novel phases, such as valence-fluctuation-induced superconductivity, near the transition associated with the collapse of the tetragonal unit cell in Eu(Fe1−xNix)2P2.
