Excitation control of bright-bright vector ghost waves with ring structures in an inhomogeneous partially nonlocal nonlinear medium

Abstract

The similar structures of coupled solitons for two-component systems were extensively discussed in literature. In this paper, the excitation management of different two-component structures for bright-bright vector ghost waves with ring structures of the inhomogeneous partially nonlocal nonlinear Schrödinger vector models under a parabolic potential is paid close attention. Considering the comparison between the maximum value of the accumulated time and the excited value of bright-bright ghost waves, the inhibition and maintenance of excitations for bright-bright ghost waves with ring structures are studied in the exponential system with the periodic modulation, and the periodical completion and periodical inhibition of excitations for bright-bright ghost waves with ring structures are discussed in the periodic modulation system. Moreover, the effect of different values of two transverse diffractions, and ring radius and thickness parameters on bright-bright ghost waves with ring structures is investigated. This study generalizes the excitation management of vector ghost waves into the partially nonlocal properties of nonlinear waves.
