论文摘要
我们研究了两个组分矢量孤子的动力学,即与奇偶元时间相互作用的明亮(bb)孤子 - ($ \ Mathcal {pt} $)对称电位。我们采用直接数值模拟来证明BB孤子的单向分离。使用修改的扰动动力学变异拉格朗日近似,我们开发了一个分析模型,以验证从数值计算中获得的结果。简化的运动方程式表明,可以通过考虑两个组件之间的有效力来解释BB孤子的分裂。
We study the dynamics of two-component vector solitons, namely, bright-bright (BB) solitons interacting with parity-time-($\mathcal{PT}$) symmetric potentials. We employ direct numerical simulations to demonstrate the unidirectional segregation of the BB soliton. Using a modified perturbed dynamical variational Lagrangian approximation, we develop an analytical model to verify the results obtained from the numerical calculations. Simplified variational equations of motion suggest that the splitting of BB solitons can be explained by considering the effective force between the two components.
