Ferromagnetism and spin excitations in topological Hubbard models with a flatband
Xiao-Fei Su, Zhao-Long Gu, Zhao-Yang Dong +2
We study the spin-1 excitation spectra of the flatband ferromagnetic phases in interacting topological insulators. As a paradigm, we consider a quarter filled square lattice Hubbar…

Topological Magnons in a One-dimensional Itinerant Flatband Ferromagnet
Xiao-Fei Su, Zhao-Long Gu, Zhao-Yang Dong +1
Different from previous scenarios that topological magnons emerge in local spin models, we propose an alternative that itinerant electron magnets can host topological magnons. A on…
