Two-dimensional Gaussian-type spatial solitons in inhomogeneous cubic-quintic-septimal nonlinear media under PT-symmetric potentials

摘要

A ()-dimensional nonlinear Schrodinger equation with cubic-quintic-septimal nonlinearities and -symmetric potentials is studied, and two kinds of Gaussian-type spatial soliton solutions are obtained. The compressed behaviors of spatial solitons are investigated in three different diffraction systems with Gaussian, Logarithmic and linear profiles. The real and imaginary parts of -symmetric potentials, the width, amplitude and phase transition of spatial solitons in different media are compared and studied.
