Abstract
Similar dynamical properties of coupled solitons have been heavily reported in previous literatures. This paper focuses on the different excitation management of two components for 3D bright-bright Peregrine triple-one structures in a nonautonomous partially nonlocal vector nonlinear Schrödinger model under a harmonic potential by contrasting the maximum accumulated time value with the excited value for each Peregrine peak. Furthermore, the different diffraction values in two transverse directions affect the bright-bright Peregrine triple-one structure configurations and amplitude and width of the Peregrine structure. This study extends the management of rogue wave to the partially nonlocal phenomena of optical wave, matter wave and other nonlinear waves.
