Topology and dynamics (A01)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277101999

The project investigates how topological states and excitations can be created and manipulated in time-dependent systems focusing on time crystals, anomalous Floquet topological phases, and corresponding quantum devices. We explore how quantum pumps and time crystals can be realized in solid state systems and how Coulomb interactions affect Floquet-Majorana states. Topological defects in space-time crystals will be studied with a focus on properties which do not have any counterpart in equilibrium.
