WebMar 17, 2024 · These Chern gaps can host fractional Chern Fermions. There has been extensive research in the RMn Sn system which hosts a small Chern gap with many trivial bands surrounding them. RMn Ge is studied theoretically in order to find a more insulating Kagome magnetic with fewer bands near the Chern gap. Submission history WebOct 14, 2024 · Kagome materials often host exotic quantum phases, including spin liquids, Chern gap, charge density wave, and superconductivity. Existing scanning microscopy studies of the kagome charge order have been limited to nonkagome surface layers. Here, we tunnel into the kagome lattice of FeGe to uncover …
