Hollow ring-like soliton and dipole soliton in (2+1)-dimensional PT-symmetric nonlinear couplers with gain and loss

By means of the Hirota bilinear method, we obtain the hollow ring-like soliton and dipole soliton solutions of the coupled nonlinear Schrödinger equation in the ( 2 + 1 )-dimensional inhomogeneous PT -symmetric nonlinear couplers. Based on these analytical solutions, we investigate the compression b...

Description
Summary:By means of the Hirota bilinear method, we obtain the hollow ring-like soliton and dipole soliton solutions of the coupled nonlinear Schrödinger equation in the ( 2 + 1 )-dimensional inhomogeneous PT -symmetric nonlinear couplers. Based on these analytical solutions, we investigate the compression behaviors of hollow ring-like soliton and dipole soliton in a diffraction decreasing system with exponential profile.
