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…
Domain walls in fractional media
Shatrughna Kumar, Pengfei Li, Boris A. Malomed
Currently, much interest is drawn to the analysis of optical and matter-wave modes supported by the fractional diffraction in nonlinear media. We predict a new type of such states,…
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…
