光晶格中具有拓扑孤子的Rice-Mele模型
Rice-Mele model with topological solitons in an optical lattice
摘要：
研究了一维周期振动光晶格中的吸引超冷费米子。在适当的共振条件下，系统实现了Rice-Mele模型描述的典型二次物理。我们系统的重要特征是可能存在受控缺陷。它们导致产生具有分数粒子数的拓扑保护局域化模式。他们可能的实验签名进行了讨论。
英文摘要：
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.
