The energy-velocity relation of a dark soliton is usually derived by its exact solution, which has been used to explain the kinetic motion of the dark soliton widely in many-body physical systems. We perform a variational method to re-derive the disp

We use the Lagrangian perturbation method to investigate the properties of soliton solutions in the coupled nonlinear Schr\"{o}dinger equations subject to weak dissipation. Our study reveals that the two-component soliton solutions act as fixed-point

Dark soliton is usually seen as one of the simplest topological solitons, due to the phase jump across its density dip. We investigate the phase jump properties of dark solitons in a single mode optical fiber with the third-order dispersion and delay
We study the dynamics of Kuznetsov-Ma solitons (KMS) in the framework of vector nonlinear Schr\"odinger (Manakov) equations. Exact multi-parameter family of solutions for such KMSs is derived. This family of solutions includes the known results as we

We report a kind of kink-like breathers in one-dimensional Bose-Einstein condensates (BECs) with helicoidal spin-orbit coupling (SOC), on whose two sides the background densities manifest obvious difference (called kink amplitude). The kink amplitude
