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…
Wannier-type photonic higher-order topological corner states induced solely by gain and loss
Ya-Jie Wu, Chao-Chen Liu, Junpeng Hou
Photonic crystals have provided a controllable platform to examine excitingly new topological states in open systems. In this work, we reveal photonic topological corner states in…
Universal intrinsic higher-rank spin Hall effect
Junpeng Hou, Ying Su, Chuanwei Zhang
Spin Hall effect (SHE), a fundamental transport phenomenon with non-zero spin current but vanishing charge current, has important applications in spintronics for the electrical con…
Non-Hermitian topological phase transitions for quantum spin Hall insulators
Junpeng Hou, Ya-Jie Wu, Chuanwei Zhang
The interplay between non-Hermiticity and topology opens an exciting avenue for engineering novel topological matter with unprecedented properties. While previous studies have main…
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…
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…
