具有随机顶点耦合的量子图的局部化

Localization on quantum graphs with random vertex couplings

Frédéric Klopp, Konstantin Pankrashkin

摘要:

研究了一类周期量子图上的薛定谔算子,该图的所有顶点具有随机分布的Kirchhoff耦合常数。利用自伴扩张技术,我们得到了一些能量相关的离散哈密顿量的有限体积准则的量子图上的局部化条件。这些条件在强无序极限和光谱边缘都成立。

英文摘要:

We consider Schrödinger operators on a class of periodic quantum graphs with randomly distributed Kirchhoff coupling constants at all vertices. Using the technique of self-adjoint extensions we obtain conditions for localization on quantum graphs in terms of finite volume criteria for some energy-dependent discrete Hamiltonians. These conditions hold in the strong disorder limit and at the spectral edges.
