Hinged Quantum Spin-Hall Effect in Antiferromagnetic Topological Insulators
Yue-Ran Ding, Dong-Hui Xu, Chui-Zhen Chen +1
In this work, we predict a hinged quantum spin-Hall (HQSH) effect featured by a pair of helical hinge modes in antiferromagnetic (AFM) topological insulator (TI) multilayers. This…
Disorder-induced Majorana zero modes in a dimerized Kitaev superconductor chain
Chun-Bo Hua, Rui Chen, Dong-Hui Xu +1
Motivated by the recent experimental observation of the topological Anderson insulator in disordered atomic wires based on the Su-Schrieffer-Heeger (SSH) model, we study disorder e…
Topological Anderson insulator phase in a quasicrystal lattice
Rui Chen, Dong-Hui Xu, Bin Zhou
Motivated by the recent experimental realization of the topological Anderson insulator and research interest on the topological quasicrystal lattices, we investigate the effects of…
Topological Superconductivity Intertwined with Broken Symmetries
Hui-Ke Jin, Dong-Hui Xu, Yi Zhou
Recently the superconductor and topological semimetal PbTaSe was experimentally found to exhibit surface-only lattice rotational symmetry breaking below . We exploit the G…
Emergent Topological Invariant and Robust Helical Edge States in Two-Dimensional Topological Metals
Chui-Zhen Chen, Hua Jiang, Dong-Hui Xu +1
In this work, we study the disorder effect on topological metals that support a pair of helical edge modes deeply embedded inside the gapless bulk states. Strikingly, we predict th…
Spatial anisotropy of Kondo screening cloud in a type-II Weyl semimetal
Lu-Ji Wang, Xing-Tai Hu, Lin Li +3
We theoretically study the Kondo screening of a spin-1/2 magnetic impurity in the bulk of a type-II Weyl semimetal (WSM) by use of the variational wave function method. We consider…
