Shape-variable four-petal Gaussian vortex breathers in strongly nonlocal nonlinear media

Shape-variable four-petal Gaussian vortex breathers in strongly nonlocal nonlinear media

In this paper, we mainly investigate the propagation properties of shape-variable four-petal Gaussian vortex breathers in strongly nonlocal nonlinear media. The analytical expression of the shape-variable four-petal Gaussian vortex breather is derived in Cartesian coordinate system by means of mathe...
