Anderson localization induced by structural disorder
AI总结：
本文研究了三维结构无序晶格中 Anderson 局域化的发生，发现随结构无序强度增加会出现局域化转变，且该转变与常规在位无序诱导的 Anderson 局域化属同一普适类。
AI中文摘要：
我们研究了在具有结构无序（以晶格不规则形式存在）且不存在任何在位无序势的三维系统中 Anderson 局域化的发生。通过分析两个具有不同类型晶格不规则性的模型，我们表明当结构无序的强度平滑增加时，会发生 Anderson 局域化转变。对结果进行有限尺寸标度分析，我们证明该转变与由在位无序诱导的常规 Anderson 局域化属于同一普适类。我们的工作识别出一类新的结构无序晶格模型，在其中物质波的相消干涉可能抑制输运，并导致金属相与局域相之间的转变。
英文摘要：
We examine the onset of Anderson localization in three-dimensional systems with structural disorder in the form of lattice irregularities and in the absence of any on-site disordered potential. Analyzing two models with distinct types of lattice regularities, we show that the Anderson localization transition occurs when the strength of the structural disorder is smoothly increased. Performing finite-size scaling analysis of the results, we show that the transition belongs to the same universality class as regular Anderson localization induced by onsite disorder. Our work identifies a new class of structurally disordered lattice models in which destructive interference of matter waves may inhibit transport and lead to a transition between metallic and localized phases.
