Nonlinear topological edge states, topological gap solitons, and self-induced topological edge states in nonlinear Su-Schrieffer-Heeger circuit lattices
Rujiang Li, Wencai Wang, Xiangyu Kong +5
Topological edge states typically arise at the boundaries of topologically nontrivial structures or at interfaces between regions with different topological invariants. When topolo…

Realization of a non-Hermitian Haldane model in circuits
Rujiang Li, Wencai Wang, Xiangyu Kong +5
The Haldane model is the simplest yet most powerful topological lattice model exhibiting various phases, including the Dirac semimetal phase and the anomalous quantum Hall phase (a…

Topological bulk solitons in a nonlinear photonic Chern insulator
Rujiang Li, Xiangyu Kong, Dongkai Hang +6
Nonlinearities in lattices with topological band structures can induce topological interfaces in the bulk of structures and give rise to bulk solitons in the topological bandgaps.…
