Topological magnon insulator spin excitations in the two-dimensional ferromagnet CrBr
Zhengwei Cai, Song Bao, Zhao-Long Gu +17
Topological magnons are bosonic analogues of topological fermions in electronic systems. They have been studied extensively by theory but rarely realized by experiment. Here, by pe…
Disorder-induced spin-liquid-like behavior in kagome-lattice compounds
Zhen Ma, Zhao-Yang Dong, Si Wu +14
Quantum spin liquids (QSLs) are an exotic state of matter that is subject to extensive research. However, the relationship between the ubiquitous disorder and the QSL behaviors is…
Comprehensive study of the global phase diagram in the triangular -- model
Shi Wang, Zhongyuan Qi, Bin Xi +3
The celebrated Kitaev honeycomb model provides an analytically tractable example with an exact quantum spin liquid ground state. While in real materials, other types of interaction…
Fractionalized Spin Excitations in the Edge Ferromagnetic State of Graphene: Signature of the Ferromagnetic Luttinger Liquid
Zhao-Yang Dong, Wei Wang, Zhao-Long Gu +2
The elementary excitations from the conventional magnetic ordered states, such as ferromagnets and antiferromagnets, are magnons. Here, we elaborate a case where the well-defined m…
Spin dynamics of a magnetic Weyl semimetal SrMnSb
Zhengwei Cai, Song Bao, Wei Wang +12
Dirac matters provide a platform for exploring the interplay of their carriers with other quantum phenomena. SrMnSb has been proposed to be a magnetic Weyl semi…
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…
