“…Soliton structures [1]- [3] excited in nonlinear evolutional systems [4]- [6] have given a great deal of help to deepen the understand of the physical mechanisms behind the actual phenomena in the areas of optical engineering [7]- [9], plasmas [10], mathematical physics [11,12] and Bose-Einstein condensates(BECs) [13,14]. Rogue wave also named as Peregrine structure(PS) has its amplitude larger over twice than waves on the background, and unexpectedly appears and then vanishes quickly without any sign [15,16].…”

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 Schr¨odinger model under a harmonic potential by contrasting the maximum accumulated time value with the 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.

“…j z ( ) Vasyliunas-Cairns velocity distribution function is a more generalized velocity distribution function that can be used to investigate the effects of suprathermal particle populations and nonthermality in the plasma system [37][38][39][40][41][42][43][44]. Singla and Saini [45] investigated the effect of polarization force on dust acoustic kinetic Alfvén solitary waves and phase portrait analysis in a magnetized dusty plasma consisting of dust and ions as well as electrons obeying Vasyliunas-Cairns distribution. Mirzaei and Motevalli [46] investigated the impact of collision angle, ion (electron) and positron unperturbed density ratios on phase shifts considering the Kappa-Cairns distribution function.…”

The combined effects of nonthermal and suprathermal particles on electrostatic modes of waves propagating in an electron-ion plasma are investigated. Vasyliunas-Cairns distribution with nonthermal and suprathermal spectral indices is used to describe the electron-ion plasma under consideration. The dispersion relation of Langmuir and ion-acoustic waves are examined using the kinetic theory approach. The population of nonthermal and suprathermal particles is found to have a considerable influence on the real wave frequency and damping rate of both Langmuir and ion-acoustic waves. The suprathermal particle population stabilizes the wave whereas the nonthermal particle population destabilizes the wave.

“…Solitary waves that have been brought to light by Scott Russel, [1] are mathematically described decades after by the elegant Korteweg-de Vries (KdV) equation. [2] The latter was also successful in delineating one-dimensional, small amplitude shallow water waves, [3] collisionless plasma Magnetohydrodynamic (MHD) waves, [4] Alfven waves, [5,6] ion-acoustic waves, [7,8,34] and matter waves. [9] Moreover, the analysis unravelled a salient feature of KdV equations, which is the possibility of solitary waves that propagate in a dispersive nonlinear medium, to interact through overtaking collisions or head-on collisions.…”

The effect of dust grain pressure on the head-on collision of two dust-acoustic solitary waves in non-magnetized, collisionless, and strongly coupled dust plasma has been investigated [J. Plasma Phys. (2020), 86, 905,860,111]. In this paper, the model is augmented by incorporating the ion drag force on dust grains. By way of the extended perturbation method of Poincaré-Lighthill-Kuo, Korteweg-de Vries equations are derived. The wave characteristics along with the phase shifts after the head-on collision are analytically established and numerically assessed. It revealed a non-negligible decrease in the wave amplitude and the phase shift.
