等谱量子图的散射

Scattering from isospectral quantum graphs

Ram Band, Adam Sawicki, Uzy Smilansky

摘要:

量子图可以推广到散射系统,当它们由通向无穷大的引线连接时。证明了对于某些扩张,等谱图的散射矩阵是共轭的,因此它们的极点分布是相同的。散射矩阵的研究使用最近发展的等谱理论。同时,散射的方法提供了一个新的见解所提到的等谱结构。

英文摘要:

Quantum graphs can be extended to scattering systems when they are connected by leads to infinity. It is shown that for certain extensions, the scattering matrices of isospectral graphs are conjugate to each other and their poles distributions are therefore identical. The scattering matrices are studied using a recently developed isospectral theory. At the same time, the scattering approach offers a new insight on the mentioned isospectral construction.
