Power-law bounds on transfer matrices and quantum dynamics in one dimension II

David Damanik, Andras Suto, Serguei Tcheremchantsev

摘要:

我们建立了一些离散的一维薛定谔算子的量子动力学下界。这些动态界来自幂律上界的规范的转移矩阵。我们进一步发展的方法,从第一部分,并研究了许多例子。特别关注的是把模型与cumberor至多可数许多例外的能量,可以证明幂律界的传递矩阵。本文讨论的模型包括替代模型、Sturmian模型、层次模型、素模型和一类中等稀疏势。

英文摘要:

We establish quantum dynamical lower bounds for a number of discrete one-dimensional Schrödinger operators. These dynamical bounds are derived from power-law upper bounds on the norms of transfer matrices. We develop further the approach from part I and study many examples. Particular focus is put on models with finitely or at most countably many exceptional energies for which one can prove power-law bounds on transfer matrices. The models discussed in this paper include substitution models, Sturmian models, a hierarchical model, the prime model, and a class of moderately sparse potentials.
