Using an optical potential with subwavelength resolution in the form of sharp $\delta$-like peaks, potential landscapes are created with increased anharmonicity in placement of lattice band energies and more favorable energy scales. In particular, this makes the ultracold atom $p$-band gas more stable. The article outlines the details of the construction and discusses the $p$-band stability in a canonical cosine optical lattice potential, double-well potential, and a combination of a classical cosine potential with dark state peaked potential.

具有大能量尺度的非谐光学晶格势中超冷原子气体的p带稳定性

使用具有亚波长分辨率的尖锐形式的光势 $\delta$像峰值一样，随着晶格带能量位置的不谐和增加和更有利的能级，创建了潜在的景观。特别是，这使超冷原子$p$带气体更稳定。本文概述了构建的细节，并讨论了$p$正弦余弦光学晶格电势，双阱电势以及经典余弦电势与暗态峰值电势的组合，具有较高的能带稳定性。
