局部扰动格点的反问题--离散哈密顿量与量子图

Inverse problems for locally perturbed lattices -- Discrete Hamiltonian and quantum graph

Emilia Blåsten, Pavel Exner, Hiroshi Isozaki, Matti Lassas, Jinpeng Lu

摘要:

本文研究了两类薛定谔算子在局部扰动周期格点上的逆散射问题。对于离散哈密顿量,所有能量的S-矩阵的知识决定了图的结构和哈密顿量的系数。对于局部扰动的等边度量图,所有能量的S-矩阵的知识决定了图的结构。

英文摘要:

We consider the inverse scattering problems for two types of Schrödinger operators on locally perturbed periodic lattices. For the discrete Hamiltonian, the knowledge of the S-matrix for all energies determines the graph structure and the coefficients of the Hamiltonian. For locally perturbed equilateral metric graphs, the knowledge of the S-matrix for all energies determines the graph structure.
