Multifarious excitations of vector combined dark-bright solitons and rogue waves with ring structures in the partially nonlocal circumstance

The partially nonlocal vector structures have been a research boom. However, the ring structure for vector combined dark-bright solitons and rogue waves is hardly reported in the partially nonlocal circumstance. This paper aims to investigate this ring structure based on the 3D nonautonomous vector partially nonlocal nonlinear Schrödinger equation with two different transverse diffractions. Exploiting the interconnected expression between nonautonomous and autonomous vector equations, and using the Darboux method, vector combined dark-bright soliton and rogue wave approximate solutions with ring structure are found. Multifarious excitations of this ring structure are analyzed in the dispersion decreasing system with Logarithmic profile. The influence of radius, thickness and Hermite parameters on this ring structure is also studied.
