Exceptional features in nonlinear Hermitian systems
Liang Fang, Kai Bai, Cheng Guo +3
Non-Hermitian systems and their topological singularities, such as exceptional points (EPs), lines, and surfaces, have recently attracted intense interest. The investigation of the…
Arbitrarily configurable nonlinear topological modes
Kai Bai, Jia-Zheng Li, Tian-Rui Liu +3
Topological modes (TMs) are typically localized at boundaries, interfaces and dislocations, and exponentially decay into the bulk of a large enough lattice. Recently, the non-Hermi…
Braiding topology of symmetry-protected degeneracy points in non-Hermitian systems
Jia-Zheng Li, Kai Bai, Cheng Guo +4
Degeneracy points in non-Hermitian systems are of great interest. While a homotopic framework exists for understanding their behavior in the absence of symmetry, it does not apply…
Spin-dependent gain and loss in photonic quantum spin Hall systems
Tian-Rui Liu, Kai Bai, Jia-Zheng Li +3
Topological phases are greatly enriched by including non-Hermiticity. While most works focus on the topology of the eigenvalues and eigenstates, how topologically nontrivial non-He…
