TT 21: Focus Session: Topological Kagome Metals

Donnerstag, 30. September 2021, 13:30–16:15, H7

The peculiar nature of the kagome lattice known to give rise exotic quantum states. When mixed with the itinerant character of the carriers, theoretically, it is predicted to host dispersionless electronic flat bands along with the linearly dispersing Dirac bands allowing one to bring together the topologically nontrivial states and the electronic correlations that lie at the center of condensed matter physics due to their roles in variety of novel quantum phenomena, such as unconventional superconductivity, heavy-fermion physics, Mott insulator states, etc. Recently, the experimental efforts caught with the predictions and several compounds are proposed as promising kagome metals, where one can realize the peculiar kagome physics in the real-world environment.
