Cascade of magnetic-field-induced quantum spin states in a spin-1 honeycomb magnet
Kaixin Tang, Zhao-Yang Dong, Yanyan Shangguan +10
Quantum fluctuations endow spin systems with surprisingly enriched magnetic phase diagrams. In frustrated magnets, strong quantum fluctuations boosted by either geometrical incompa…
Relationship between doping-induced in-gap states and spin excitations in Kitaev-Hubbard models
Si-Qi Hou, Shun-Li Yu, Zhao-Yang Dong +1
We investigate the connection between doping-induced in-gap states and underlying spin excitations in Mott insulators by employing cluster perturbation theory on one-dimensional (1…
Interaction-driven spin polaron in itinerant flat-band ferromagnetism
Wei-Tao Zhou, Zhao-Yang Dong, Jian-Xin Li
Interaction effects are dramatically enhanced in flat-band systems due to quenched kinetics, facilitating the binding of single excitations into composite quasiparticles. In this w…
