Quiescent and traveling solitons in the fractional parametrically driven damped nonlinear Schrödinger equation
Dongdong Wang, Rujiang Li, David Laroze +2
We systematically investigate the existence, stability, and dynamics of optical solitons in the framework of the one-dimensional nonlinear Schrödinger equation with the Riesz-frac…
Parametrically driven pure-quartic solitons
Pengfei Li, Lijing Xing, Dongdong Wang +3
Parametrically driven solitons are self-trapped modes in various physical settings, including optics, magnetics, etc. So far, the analysis was focused on the existence, stability,…
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…
Transformation of topological optical states via spiral modulation in fractional-diffraction systems
Dongdong Wang, Xueqing He, Rujiang Li +3
We propose a scheme for manipulations of a variety of topological states in fractional optical systems through spiral modulation of the local refraction index. An analytical approx…
Pure-quartic domain-wall solitons as topological bits for data transmission
Pengfei Li, Jun Ruan, Shilong Liu +2
Domain walls (DWs) are topological defects produced by symmetry-breaking phase transitions. Although DWs have been the subject of much work due to their fundamental physical proper…
Effects of fractional diffraction on nonlinear PT phase transitions and stability of dark solitons and vortices
Xueqing He, Mingming Zhang, Pengfei Li +2
The wave propagation under the action of fractional diffraction has recently drawn increasing attention in nonlinear optics. Here, we address the effect of fractional diffraction o…
