New Soliton Applications in Earth's Magnetotail Plasma at Critical Densities

Abstract

New plasma wave solutions of the modified Kadomtsev Petviashvili (MKP) equation are presented. These solutions are written in terms of some elementary functions, including trigonometric, rational, hyperbolic, periodic, and explosive functions. The computational results indicate that these solutions are consistent with the MKP equation, and the numerical solutions indicate that new periodic, shock, and explosive forms may be applicable in layers of the Earth's magnetotail plasma. The method employed in this paper is influential and robust for application to plasma fluids. In order to depict the propagating soliton profiles in a plasma medium, the MKP equation must be solved at critical densities. In order to achieve this, the Riccati-Bernoulli sub-ODE technique has been utilized in solutions. The research findings indicate that a number of MKP solutions may be applicable to electron acoustics appearing in the magnetotail.

The new stochastic solutions for three models of non-linear Schrödinger’s equations in optical fiber communications via Itô sense

“…The subject of non-linear waves has become increasingly important in layers of the Earth's magnetotail plasma [1], liquid crystals [2], fluid dynamics [3], gas-liquid [4], plasma [5], birefringent fibers [6], and non-linear optics [7]. These waves describe so many complex phenomena and are reflected in the form of deterministic or stochastic non-linear partial differential equations (NPDEs), such as the resonant non-linear Schrödinger equation [8], the Phi-4 equation and foam drainage equation [9], the system of ISALWs [10], and the (1 + 1)-dimensional Benjamin-Bona-Mahony and (2 + 1)-dimensional asymmetric Nizhnik-Novikov-Veselov equations [11].…”

Nonlinear harmonics coupled by parallel wave propagations in a time-dependent plasma flow

“…In the linear assumption, the modes are independent and their interaction is ignored. However, plasmas involve nonlinearly coupled fields and associated particle motions [17][18][19][20]. Even when the intensity of a nonlinearly excited wave is small compared to a linear wave, the nonlinear wave can carry information of a plasma or trigger instabilities [17,[21][22][23].…”
