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…
Magnon Damping as a Probe of Kondo Coupling in Magnetically Ordered Systems
Song Bao, Junsen Wang, Shin-ichiro Yano +13
In -electron systems, there can also be intricate interplay between Kondo coupling and magnetic interactions as that in -electron systems, but the underlying mechanism remain…
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…
Itinerant topological magnons and spin excitons in twisted transition metal dichalcogenides: Mapping electron topology to spin counterpart
Wei-Tao Zhou, Zhao-Yang Dong, Zhao-Long Gu +1
Twisted transition metal dichalcogenides (tTMDs) provide a highly tunable platform to explore the interplay between strong correlation and topology. Among them, the properties invo…
Ligand-SOC enhanced Kitaev antiferromagnet: Application to
Li-Hao Xia, Yi-Peng Gao, Zhao-Yang Dong +1
The search for Kitaev quantum spin liquids (Kitaev-QSLs) in real materials has mainly focused on - and -electron honeycomb systems. A recent experimental study on the $4f^5…
