Quantum materials with strong elastic coupling (A11)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 422213477

The project focuses on quantum materials with a non-perturbative elastic coupling. Considering materials close to a quantum-critical point, the project will theoretically investigate the coupling of critical fluctuations to crystal elasticity. Two examples will be considered, the isotropic ferroelectric quantum critical point and the Lifshitz transition of a two-dimensional metal, with a particular focus on the stability of the crystal lattice in the presence of these critical fluctuations.
