论文摘要
光学晶格中具有超速原子的大多数实验都具有接触相互作用,因此在每个位置的一个原子大约一个原子的高密度下进行,以观察强相互作用的效果。可以通过Rydberg敷料产生强范围的相互作用,这为探索很少的相互作用颗粒的物理学开辟了道路。现在可以将光学晶格的位点解释为离散空间,而不是晶体的单位单元。这允许在熟悉的体系结构中研究全新的问题。我们研究了类似于量子化学中发现的问题的可能性,尽管相互作用中的比例定律不同。通过数值模拟,我们表明可以在最先进的实验中以高保真度制备简单的伪原子和 - 分子。
Most experiments with ultracold atoms in optical lattices have contact interactions, and therefore operate at high densities of around one atom per site to observe the effect of strong interactions. Strong ranged interactions can be generated via Rydberg dressing, which opens the path to explore the physics of few interacting particles. Rather than the unit cells of a crystal, the sites of the optical lattice can now be interpreted as discretized space. This allows studying completely new types of problems in a familiar architecture. We investigate the possibility of realizing problems akin to those found in quantum chemistry, although with a different scaling law in the interactions. Through numerical simulation, we show that simple pseudo-atoms and -molecules could be prepared with high fidelity in state-of-the-art experiments.
