Spatial solitons, beams that do not spread owing to diffraction when they propagate, have
been demonstrated to exist by virtue of a variety of nonlinear self-trapping mechanisms …

Ultrafast fiber lasers have significant applications in laser communications, ultra-precision
manufacturing, biomedical diagnostics, and so on. Among all the types of ultrashort pulses …

We obtain the nondegenerate one-and two-soliton solutions of the nonlocal nonlinear
Schrödinger equation by using the nonstandard Hirota method. This unconventional method …

In the fiber communication domain, people are facing the challenges due to the rapidly
growing requirement on the capacity from new functions and services. Multi-hump solitons …

Solitons are self-localized wave packets arising from a robust balance between dispersion
and nonlinearity. They are a universal phenomenon, exhibiting properties typically …

In this paper, we investigate the optical nondegenerate solitons in a birefringent fiber with a
35 degree elliptical angle. We derive the nondegenerate bright one-and two-soliton …

We present the exact bright one-soliton and two-soliton solutions of the integrable three
coupled nonlinear Schrödinger equations (3-CNLS) by using the Hirota method, and then …

Ultracold gases provide an unprecedented level of control for the investigation of soliton
dynamics and collisions. We present a scheme for deterministically preparing pairs of three …

Particle-like structures of solitons, as a result of the balance between dispersion and
nonlinearity, enable remarkable elastic and inelastic soliton collisions in many fields …

We propose superluminal solitons residing in the momentum gap (k gap) of nonlinear
photonic time crystals. These gap solitons are structured as plane waves in space while …
