Second-order and real Chern topological insulator in twisted bilayer -graphyne
Bin-Bin Liu, Xu-Tao Zeng, Cong Chen +2
The study of higher-order and real topological states as well as the material realization have become a research forefront of topological condensed matter physics in recent years.…
Doping-induced structural transformation in the spin-1/2 triangular-lattice antiferromagnet NaBaSrCo(PO)
Chuandi Zhang, Qianhui Xu, Xu-Tao Zeng +10
The effects of Sr doping on the structural properties of NaBaCo(PO), a spin-1/2 triangular-lattice antiferromagnet as a quantum spin liquid candidate, are investi…
Zigzag magnetic order in a novel tellurate compound NaNiTeO with = 1 chains
Cheng Su, Xu-Tao Zeng, Yi Li +9
NaNiTeO is a rare example in the transition-metal tellurate family of realizing an = 1 spin-chain structure. By performing neutron powder diffraction measurements…
Topological hinge modes in Dirac semimetals
Xu-Tao Zeng, Ziyu Chen, Cong Chen +3
Dirac semimetals (DSMs) are an important class of topological states of matter. Here, focusing on DSMs of band inversion type, we investigate their boundary modes from the effectiv…
