New Gaussian Solitary Wave Solutions in Nanofibers

The article studies the dynamics of Gaussian solitary waves in nano optical fibers which are described by perturbed and improved nonlinear Schrodinger equations which have logarithmic nonlinearities with and without attenuation terms. As a result, the Gaussian solitary waves have been extracted for the logarithmic perturbed nonlinear Schrodinger equation and the logarithmic perturbed improved nonlinear Schrodinger equation. Moreover, new logarithmic improved nonlinear Schrodinger equations are presented. With the Gaussian function and symbolic computation, we obtain the Gaussian solitary waves for such equations.
