Global band topology: from point crossings to nodal planes (A06)

• Subject Area: Experimental Condensed Matter Physics ; Theoretical Condensed Matter Physics
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 492547816

Topological materials are of interest both for fundamental research and applications in spintronics and quantum technology. These materials exhibit a diverse set of different band topologies, including Weyl points, multifold band crossings, and nodal planes. In this project we combine theoretical band topology calculations with quantum oscillation experiments to (i) study the interdependence among multiple band topologies, (ii) devise generic means to place the band topologies at the Fermi level, and (iii) work out methods to efficiently control the band topology by external tuning parameters.
