论文摘要
我们研究了在存在由二甲酸二孔非线性的情况下,由二甲酸非线性与外部来源建模的二甲酸非线性,并具有平均时间对称潜力的波导偶联的Bose-Einstein冷凝物的动力学。我们采用自相似技术来获得物质波解决方案,例如该模型的明亮,扭结,理性的黑暗和洛伦兹型自相似波。自相似物质波的动态行为可以通过系统中存在的非线性的诱捕潜力,外部来源和性质的变化来控制。
We study the dynamics of Bose-Einstein condensate coupled to a waveguide with parity-time symmetric potential in the presence of quadratic-cubic nonlinearity modelled by Gross-Pitaevskii equation with external source. We employ the self-similar technique to obtain matter wave solutions, such as bright, kinktype, rational dark and Lorentzian-type self-similar waves for this model. The dynamical behavior of self-similar matter waves can be controlled through variation of trapping potential, external source and nature of nonlinearities present in the system.
