Symmetry-breaking bifurcation of coupled topological edge states
Rujiang Li, Letian Xu, Muhammad Imran +3
We propose that the symmetry-breaking bifurcation of coupled topological edge states (CTESs) can be used as a general principle for achieving spontaneous symmetry breaking (SSB) in…
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…
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.…
Self-localized topological states in three dimensions
Rujiang Li, Pengfei Li, Yongtao Jia +1
Three-dimensional (3D) topological materials exhibit much richer phenomena than their lower-dimensional counterparts. Here, we propose self-localized topological states (i.e., topo…
