In this paper, a Lakshmanan-Porsezian-Daniel equation, which describes the nonlinear spin
excitations in a (1+ 1)-dimensional isotropic biquadratic Heisenberg ferromagnetic spin …

Fluid mechanics is seen as the study on the underlying mechanisms of liquids, gases and
plasmas, and the forces on them. In this paper, we investigate a (2+ 1)-dimensional …

Investigated in this paper is an extended (3+ 1)-dimensional Kadomtsev-Petviashvili
equation. We determine the N-soliton solutions of that equation via an existing bilinear form …

Optical fiber communication plays an important role in the modern communication. In this
paper, we investigate a variable-coefficient coupled Hirota system which describes the …

Pure-quartic solitons (PQSs) with higher energy in short pulse width have been generated in
the mode-locked fiber laser recently, and soliton molecules have been found as a means to …

With the rapid development of communication technology, optical fiber communication has
become a key research area in communications. When there are two signals in the optical …

Spin waves, usually used in radar and communication system, are the collective excitation of
spin system in ferromagnetic metals, and considered as potential data carriers for computing …

A nonlinear Schrödinger equation with the combined effects of variable nonlinearity and
generalized external potentials is investigated. Three soliton solutions are generated by …

In this study, we consider the third order nonlinear Schrödinger equation (TONSE) that
models the wave pulse transmission in a time period less than one-trillionth of a second …

Soliton interactions occur when two solitons are close enough. In general, periodic
oscillations can be presented during soliton interactions. The periodic oscillations will lead …
