摘要
We find analytical vortex wave solutions in a strongly nonlocal thermal nonlinear medium with square boundaries. We investigate the dynamics of superposed vortex waves with different topological charges by propagating them for a long distance. We show that the presence of a linear term in the proposed model, which otherwise is the model for the accessible soliton model, results in the formations of various transformation patterns and stable structures during the unstable superposed vortex waves propagation. Some previously found stable solitons, such as the necklace vortex soliton and the Laguerre-Gaussian solitons, were found, and new stable structures, such as the quadrupole soliton and the "petal"-shaped soliton, were shown to form during unstable superposed vortex waves propagation.
