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。
In this paper, the soliton scattering in PT-symmetry Gaussian potential was discussed bynumerical stimulation, including the evolution dynamics, transmission dynamics of the amplitude and initialflow within some parameters range, and can manipulate the scattering direction of the soliton by choosingsuitably the potential parameters.
