Light polarons with electron-phonon coupling
Chao Zhang
In most cases, as the strength of electron-phonon coupling increases, the effective mass of polarons typically increases. However, in this paper, we uncover a fascinating phenomeno…
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…
Spinon Majorana fermions
Rui Wang, Hong-Yan Lu, Baigeng Wang +1
A realization of Majorana fermions is proposed in the frustrated magnets via the topological proximity effect. Specifically, we consider a theoretical model, where a topological in…
