我们介绍了一种简单的设置，对应于嵌入光子晶体中并与辐射场相互作用的杂质原子的物质波模拟。给定内部能级的原子被捕获在光学晶格中，并起到杂质的作用。未捕获能级中的原子起到辐射场的作用。这种相互作用是通过耦合这些能级的激光来介导的。通过调整激光器参数，可以驱动系统通过不同的状态，并观察物质波超辐射、非马尔可夫原子发射和束缚原子态的出现等现象。
We introduce a simple setup corresponding to the matter-wave analogue of impurity atoms embedded in a photonic crystal and interacting with the radiation field. Atoms in a given internal level are trapped in an optical lattice, and play the role of the impurities. Atoms in an untrapped level play the role of the radiation field. The interaction is mediated by means of lasers that couple those levels. By tuning the lasers parameters, it is possible to drive the system through different regimes, and observe phenomena such as matter-wave superradiance, non-Markovian atom emission, and the appearance of bound atomic states.
