Magnetic topological kagome systems
Julian Legendre, Karyn Le Hur
Abstract
The authors introduce a new class of topological systems driven by the Hund's coupling mechanism associated to Mott physics. The paper establishes a link between the core magnetism on the Kagome lattice and the occurrence of topological energy Bloch bands. This research is motivated by the recently discovered quantum material Co3Sn2S2.
