Hamburg Photon Science Colloquium | Topological materials science

by Claudia Felser (Max Planck Institute for Chemical Physics of Solids, Dresden, Germany)


Topology, a mathematical concept, recently became a hot and truly transdisciplinary topic in condensed matter physics, solid state chemistry and materials science. All 200 000 inorganic materials were recently classified into trivial and topological materials: topological insulators, Dirac, Weyl and nodal - line semimetals, and topological metals. Beyond Weyl and Dirac, new fermions can be identified in compounds that have linear and quadratic 3-, 6- and 8- band crossings that are stabilized by space group symmetries. Around 20% of all materials host topological bands. Currently, we have focussed also on magnetic materials, a fertile field for new since all crossings in the band structure of ferromagnets are Weyl nodes.


IMPORTANT INFORMATION: The Hamburg Photon Science Colloquium will be put on video using the recording function of zoom. When recording is started a pop-up window appears and you have the choice to continue your participation or to leave the meeting; by continuing your participation you consent to recording.
