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…

Nonlinear quadrupole topological insulators
Rujiang Li, Wencai Wang, Yongtao Jia +3
Higher-order topological insulators (HOTIs) represent a family of topological phases that go beyond the conventional bulkboundary correspondence. d-dimensional n-th order HOTIs mai…

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…
