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…

Spectral properties of the square-lattice antiferromagnetic J1-J2 Heisenberg model: confinement and deconfinement of spinons
Shun-Li Yu, Wei Wang, Zhao-Yang Dong +2
Based on the mapping between spin operators and hard-core bosons, we extend the cluster perturbation theory to spin systems and study the whole excitation spectrum of the a…

Dynamics of a single hole in the Heisenberg-Kitaev model: a self-consistent Born approximation study
Bin-Bin Wang, Wei Wang, Shun-Li Yu +1
The magnetic properties of 4d and 5d transition-metal insulating compounds with the honeycomb structure are believed to be described by the Heisenberg-Kitaev model, which contains…
