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…
Correlation-Driven Orbital-Selective Fermiology and Superconductivity in the Bilayer Nickelate LaNiO
Yong-Yue Zong, Shun-Li Yu, Jian-Xin Li
Recent angle-resolved photoemission measurements on LaNiO have challenged the density-functional-theory-based picture of three Fermi surfaces by revealing that the $d_{…
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…
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…
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…
Pseudogap with Fermi arcs and Fermi pockets in half-filled twisted transition metal dichalcogenides
Yong-Yue Zong, Zhao-Long Gu, Jian-Xin Li
Twisted transition metal dichalcogenides are a new platform for realizing strongly correlated physics with high tunability. Recent transport experiments [A. Ghiotto et al. Nature 5…
Spectrum of the hole excitation in spin-orbit Mott insulator NaIrO
Wei Wang, Zhao-Yang Dong, Shun-Li Yu +1
We study the motion of a hole with internal degrees of freedom, introduced to the zigzag magnetic ground state of NaIrO, by using the self-consistent Born approximation. We…
Discovery of coexisting Dirac and triply degenerate magnons in a three-dimensional antiferromagnet
Song Bao, Jinghui Wang, Wei Wang +11
Topological magnons are emergent quantum spin excitations featured by magnon bands crossing linearly at the points dubbed nodes, analogous to fermions in topological electronic sys…
