Abstract

We predict a generic mechanism of wave localization at an interface between uniform artificial gauge fields, arising due to propagation-dependent phase accumulation similar to Aharonov-Bohm phenomenon. We realize experimentally a synthetic mesh lattice with real-time control over the vector gauge field, and observe robust localization under a broad variation of gauge strength and direction, as well as structural lattice parameters. This suggests new possibilities for confining and guiding waves in diverse physical systems through the synthetic gauge fields.

摘要

我们预测了一种在均匀人工规范场界面处波局域化的通用机制，这是由于与阿哈罗诺夫 - 玻姆现象类似的与传播相关的相位积累而产生的。我们通过实验实现了一种对矢量规范场具有实时控制的合成网格晶格，并在规范强度、方向以及结构晶格参数的广泛变化下观察到了稳健的局域化现象。这为通过合成规范场在各种物理系统中限制和引导波提供了新的可能性。
