Novel Dynamics of a Vortex in Three-Dimensional Dissipative Media with an Umbrella-Shaped Potential

We report the novel dynamic of 3D dissipative vortices supported by an umbrella-shaped potential （USP） in the 3D complex Ginzburg-Landau （GGL） equation with the cubic-quintic nonlinearity. The stable solution of vortices with intrinsic vorticity S=1 and 2 are obtained in the 3D GGL equation. An appropriate USP forces the vortices continuously to throw out fundamental 3D solitons （light bullets） along the folding umbrella. The dynamic regions of the strength of the potential with the changing number of folding umbrella are analyzed, and the rate of throwing increases with the strength of the potential. A weak potential cannot provide vortices with enough force. Then, the vortices will be stretched into polygons. However, a strong potential will destroy the vortices.
