本文探讨了一维周期性摇摆光学晶格中的超冷原子系统，在共振摇摆条件下，系统展现出Rice-Mele模型所描述的二维量子效应。特别关注的是，可控的缺陷创造了具有拓扑保护的局域化模式，承载了分数粒子数。文章详细讨论了这些现象的实验可能迹象。
摘要：
Attractive ultra-cold fermions trapped in a one-dimensional periodically shaken opticla lattices are considered. For an appropriate resonant shaking the system realizes paradigmatic dimes physics described by Rice-Mele model. The important feature of our system is the possible presence of controlled defects. They result in the creation of topologically protected loclaized modes carrying fractional particle number. Their possible experimental signatures are discussed.
