Optical solitons for the concatenation model with fractional temporal evolution
Ain Shams Engineering JournalThis paper recovers the optical solitons for the concatenation model that comes with fractional temporal evolution and Kerr–law of self–phase modulation by the usage of the enhanced direct algebraic approach.

The symmetries of solitons [PDF]
Bulletin of the American Mathematical Society, 1997 In this article we will retrace one of the great mathematical adventures of this century—the discovery of the soliton and the gradual explanation of its remarkable properties in terms of hidden symmetries. We will take an historical approach, starting with a famous numerical experiment carried out by Fermi, Pasta, and Ulam on one of the first ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study investigates the effects of oxidation treatment on the nonlinear optical absorption properties and carrier dynamics of two‐dimensional violet phosphorene (VP), elucidating the underlying physical mechanisms. Furthermore, ultrashort laser pulses are achieved utilizing the enhanced saturation absorption and shortened carrier relaxation ...

THE SOLITON–SOLITON INTERACTION IN THE CHIRAL DILATON MODEL [PDF]
International Journal of Modern Physics A, 2013 We study the interaction between two B = 1 states in the Chiral Dilaton Model where baryons are described as nontopological solitons arising from the interaction of chiral mesons and quarks. By using the hedgehog solution for B = 1 states we construct, via a product ansatz, three possible B = 2 configurations to analyse the role of the relative ...

Strain Imaging of GaAs by Stimulated Raman Scattering Microscopy
Journal of Raman Spectroscopy, EarlyView.Telecom‐wavelength stimulated Raman scattering (SRS) microscopy is developed for high‐throughput, nondestructive characterization of gallium arsenide (GaAs). By overcoming optical absorption limits of conventional Raman systems, this technique enables precise visualization of LO phonon frequency variations (< 0.2‐cm−1$$ {}^{-1} $$ precision).

Oscillatory soliton pairs in spin-orbit coupled spin-1/2 Bose–Einstein condensates
New Journal of PhysicsWe investigate oscillatory soliton pairs including the bright–bright solitons, dark–dark solitons, bright–dark solitons and beating solitons (beating soliton refers to a type of soliton characterized by components that are each composed of both bright ...

Emergence of Solitons from Irregular Waves in Deep Water
Journal of Marine Science and Engineering, 2021 Numerical simulations were performed to study the long-distance evolution of irregular waves in deep water. It was observed that some solitons, which are the theoretical solutions of the nonlinear Schrödinger equation, emerged spontaneously as irregular ...
