基于PT对称高斯势的孤子单向散射的操控
Manipulation of Soliton Scattering in PT-symmetry Gaussian Potential
摘要
本文运用数值模拟的方法讨论在PT对称高斯势中孤子的散射问题,包括演化动力学,孤子振幅和质心位置的传输动力学以及PT对称高斯势对孤子单向散射特性的影响。结果表明在一定的参数范围内,单个孤子或孤子串的散射都能展现出单向流的特性,并且可以通过适当地调节PT对称高斯势的参数来实现孤子单向散射的操控。
Abstract
In this paper,the soliton scattering in PT-symmetry Gaussian potential was discussed by numerical stimulation,including the evolution dynamics,transmission dynamics of the amplitude and initial center-of-mass position of the soliton and the influence of PT symmetry potential to soliton unidirectional scattering properties. The results showed that single soliton or a train of solitons can exhibit the directional flow within some parameters range,and can manipulate the scattering direction of the soliton by choosing suitably the potential parameters.
