摘要 安德森本地化一直是一个激烈的主题, 研究多年。在此背景下,我们研究 在数值上, 在一维系统中的局部化行为。我们 调查本地化长度和密度 状态,并将我们的数值结果与解析结果进行比较 预测。具体来说,我们发现了两个不同的 带中心附近的特征行为 和未受干扰的带边缘。此外 我们解决了固有的短程效应, 相关性
Abstract Anderson localization has been a subject of intense studies for many years. In this context, we study numerically the influence of long-range correlated disorder on the localization behavior in one dimensional systems. We investigate the localization length and the density of states and compare our numerical results with analytical predictions. Specifically, we find two distinct characteristic behaviors in the vicinity of the band center and at the unperturbed band edge, respectively. Furthermore we address the effect of the intrinsic short-range correlations.
