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…
