Bright solitons for the coupled cubic-quintic non-linear Schrödinger equations
TL;DR: In this paper, the effects of quintic non-linearity on the ultra-short optical-pulse propagation in the non-Kerr medium were investigated, and the bright two solitons kept their original amplitudes, widths and velocities invariant after each collision except for the phase shifts.

Soliton-like solutions and chaotic motions for a forced and damped Zakharov–Kuznetsov equation in a magnetized electron–positron–ion plasma
TL;DR: In this article, a forced and damped Zakharov-Kuznetsov equation for a magnetized electron-positron-ion plasma affected by an external force is studied via the Hirota method.

Optical-soliton and chaotic motions in a nonlocal nonlinear medium
TL;DR: In this article, the coupled equations for the incoherent optical spatial solitons in a non-local nonlinear medium are studied analytically, and the chaotic motions in the nonlinear nonlocal medium, including effects of the external forces on suc...

Dark solitons and rouge waves for a (2+1)-dimensional Gross–Pitaevskii equation with time-varying trapping potential in the Bose–Einstein condensate
TL;DR: In this paper, a (2+1)-dimensional Gross-Pitaevskii equation with time-varying trapping potential was investigated, and the dark one-soliton, two-solon, three-solons, breather-wave and rouge-wave solutions were obtained.
