AI总结:

本文针对度量图上的非局域非线性薛定谔方程,利用势方法推导透明边界条件以消除顶点背向散射,从而降低信号、热和电荷传输损耗。

摘要:

我们研究了在度量图上以非局域非线性薛定谔方程(NNLS)建模的网络中的无反射波传播,其中在顶点处施加透明边界条件。通过采用先前用于非线性薛定谔方程的“势方法”,我们推导出度量图上NNLS方程的透明边界条件。这些条件消除了图顶点处的背向散射,这对于在光纤、光电网络和低维材料等各种应用中最小化信号、热量和电荷传输的损耗至关重要。

英文摘要:

We consider reflectionless wave propagation in networks modeled in terms of the nonlocal nonlinear Schrödinger (NNLS) equation on metric graphs, for which transparent boundary conditions are imposed at the vertices. By employing the ``potential approach" previously used for the nonlinear Schrödinger equation, we derive transparent boundary conditions for the NNLS equation on metric graphs. These conditions eliminate backscattering at graph vertices, which is crucial for minimizing losses in signal, heat, and charge transfer in various applications such as optical fibers, optoelectronic networks, and low-dimensional materials.
