Quantum spin-tensor Hall effect protected by pseudo time-reversal symmetry
Ya-Jie Wu, Tong Li, Junpeng Hou
The celebrated family of the Hall effect plays a fundamental role in modern physics. Starting from the anomalous Hall effect (AHE) and the quantum AHE (QAHE) with broken time-rever…
Higher-order Topological Phases of Magnons in van der Waals Honeycomb Ferromagnets
Yun-Mei Li, Ya-Jie Wu, Xi-Wang Luo +2
We theoretically propose a second-order topological magnon insulator by stacking the van der Waals honeycomb ferromagnets with antiferromagnetic interlayer coupling. The system exh…
Higher-order topological corner states induced solely by onsite potentials with mirror symmetry
Ya-Jie Wu, Wen He, Ning Li +2
Higher-order topological insulators have triggered great interests because of exhibitions of non-trivial bulk topology on lower-dimensional boundaries like corners and hinges. Whil…
Two-dimensional non-Hermitian topological phases induced by asymmetric hopping in a one-dimensional superlattice
Junpeng Hou, Ya-Jie Wu, Chuanwei Zhang
Non-Hermitian systems can host topological states with novel topological invariants and bulk-edge correspondences that are distinct from conventional Hermitian systems. Here we sho…
Symmetry-protected localized states at defects in non-Hermitian systems
Ya-Jie Wu, Junpeng Hou
Understanding how local potentials affect system eigenmodes is crucial for experimental studies of nontrivial bulk topology. Recent studies have discovered many exotic and highly n…
In-plane Zeeman field induced Majorana corner and hinge modes in an -wave superconductor heterostructure
Ya-Jie Wu, Junpeng Hou, Yun-Mei Li +3
Second-order topological superconductors host Majorana corner and hingemodes in contrast to conventional edge and surface modes in two and three dimensions. However, the realizatio…
