Static and dynamic control of excitations in Quantum Anomalous Hall systems (B07)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277146847

The quantum anomalous Hall insulator is a ferromagnetic topological insulator hosting an edge state propagating around an insulating bulk. With robust transport signatures, it offers a perfect playground for advanced fundamental experiments and innovative devices with applications. In this material, we will use a combination of low- and high-frequency transport methods to create domain walls, explore the dynamics of topological edge channels, and realize compact microwave circulator devices.
