Harper-Hofstadter模型的局域化程度对相自由度表现出显著的周期性依赖关系，这取决于边界条件的性质，这让人想起Aharonov-Bohm效应。在有限环形晶格结构中实现的情况下，这种相依性可以被用作基于局部化而不是基于干涉测量的旋转和磁场的精确传感的根本不同的原理。
The degree of localization of the Harper-Hofstadter model is shown to display striking periodic dependence on phase degrees of freedom, which can depend on the nature of the boundary condition, reminiscent of the Aharonov-Bohm effect. In the context of implementation in a finite ring-shaped lattice structure, this phase dependence can be utilized as a fundamentally different principle for precision sensing of rotation and magnetic fields based on localization rather than on interferometry.
