Exploring the optical soliton and solitary wave solutions for the nonlinear Akbota equation via improved expansion approach

open access: yesAIP Advances
In the present research, we explored the various kinds of optical solitons and many other solitary wave solutions for the nonlinear Akbota equation by utilizing the symbolic computational simulation on the basis of the improved F-expansion approach.

Application of picosecond optical guiding-center solitons in single-mode fibers to precise synchronization of a radio-interferometer [PDF]

open access: yes, 2007
Picosecond optical guiding-center solitons of the first order, peculiar for the cubic Ginzburg–Landau systems, are considered as the sync-signal carriers, being attractive for the transmission through optical fiber network. At first, we analyze the model,

Complex sine-Gordon theory: solitons, defects and boundaries [PDF]

open access: yes, 2008
This thesis presents research into the properties and features of the complex sine- Gordon theory. The CSG theory is a dimensional integrable held theory that admits soliton solutions which carry a Noether charge due to the U(I) invariance of the theory.

Helmholtz dark solitons

open access: yes, 2003
A general dark-soliton solution of the Helmholtz equation (with defocusing Kerr nonlinearity) that has on- and off-axis, gray and black, paraxial and Helmholtz solitons as particular solutions, is reported.
