Stable dissipative topological solitons in media with even-order dispersion
Xianan Sun, Dongdong Wang, Dumitru Mihalache +3
The formation and dynamics of dissipative solitons are governed by the interplay of dispersion and nonlinearity, alongside the gain-loss balance. While it is known that dispersion…

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,…

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…
