论文摘要
我们对eRatosthenes算法的古代筛子的几何类似物进行了分类，并揭示了已知的光学莫伊尔晶格和露出异国情调的晶格配置。从飞行时间干扰模式的数值模拟中揭示了装入这些光学晶格中的Bose-Einstein冷凝物的丰富动力学。设定这种方法的原因是能够在不改变激光波长的情况下调整光学晶格的周期性，但在各个晶格位点保持局部电位。此外，我们讨论了仅通过应用结构化相通过空间转换光学晶格的能力。
We catalog known optical moiré lattices and uncover exotic lattice configurations following a geometric analog of the ancient sieve of Eratosthenes algorithm for finding prime numbers. Rich dynamics of Bose-Einstein condensates loaded into these optical lattices is revealed from numerical simulations of time-of-flight interference patterns. What sets this method apart is the ability to tune the periodicity of the optical lattices without changing the wavelength of the laser, yet maintaining the local potential at the individual lattices sites. In addition, we discuss the ability to spatially translate the optical lattice through applying a structured phase only.
