摘要

本文研究了具有次指数长程跳变和log-Hölder连续分布势的Zd上的Anderson紧密结合模型。证明了在高无序状态下，该模型具有具有亚指数衰减特征函数的纯点谱。这部分地回答了欧罗巴的一个猜想。生态学报，（1987）：1061-1065。我们的证明是基于多尺度分析型格林函数估计。

Sub-exponential localization for a random tight-binding model with long-range hopping

In this paper, we study the Anderson tight-binding model on

Z^{d}

with the sub-exponential long-range hopping and log-Hölder continuously distributed potential. It is proved that, at high disorder this model has pure point spectrum with sub-exponentially decaying eigenfunctions. This gives a partial answer to a conjecture of Yeung-Oono [Europhys. Lett. 4(9), (1987): 1061-1065]. Our proof is based on multi-scale analysis type Green's function estimates.
