Optical conductivities and entanglement in magnetic topological semimetals (A05)

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

In this project we study a variety of topological materials from the family of the Kagome magnets which are relevant for the experimental efforts of the overall project. In this context our aim is twofold. First, we plan to develop and apply material-specific theoretical tools with predictive power for spectral probes, i.e., diagonal and off-diagonal conductivities. This will be achieved by performing material-specific as well as model calculations combining Density Functional Theory with many body physics using Dynamical Mean Field Theory and its cluster extensions. Second, we aim to use these methods in order to make material-specific predictions on multipartite quantum entanglement through the quantum Fisher information.
