Dynamics of ion Coulomb crystals (A07)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 274200144

This project explores the dynamics of ion Coulomb crystals (ICC), focusing on structural defects, phase transitions and the behavior of vibrons and polaritons, using advanced cooling methods. It investigates energy transport in two-dimensional structures and the effects of crystal defects. Key studies include the energy blockade by topological defects, polariton dynamics in complex geometries, and the impact of defects on driven-dissipative regimes. The project also extends to nanofriction in mixed-species and three-dimensional crystals, examining defect interactions and the influence of highly charged ions on the crystal stability. This research advances our understanding of quantum many-body dynamics, relevant for quantum metrology and information experiments.
