TL;DR: In this paper, a numerical examination of propagating nonlinear dissipative dust-acoustic breathers and rogue waves in electron depleted dusty plasmas having two superthermal ions of different temperature has been made.
Abstract: In this paper, a numerical examination of propagating nonlinear dissipative dust-acoustic breathers and rogue waves (RWs) in electron depleted dusty plasmas having two superthermal ions of different temperature has been made. An important ingredient in this study is the inclusion of the dissipative effect due to the viscosity of the dust grains in the evolution wave equation. Accordingly,
a damped/modified nonlinear Schr?dinger equation (DNLSE), i.e. the standard nonlinear Schr?dinger equation (NLSE) in addition to the damping term, is obtained using a reductive perturbation (the derivative expansion) method. Without taking into account the effect of dust viscosity, the standard NLSE is also examined, and the effect
of relevant physical parameters on the breathers and rogue waves is examined. Moreover, the impact of dust kinetic viscosity on both breather structures and RWs is investigated by solving DNLSE numerically
with the Dirichlet boundary conditions. This model may be
useful to understand the excitation of dust-acoustic waves in the Earth’s magnetotail.
