We describe a method for controlling many-body states in extended ensembles of Rydberg atoms, forming crystalline structures during laser excitation of a frozen atomic gas. Specifically, we predict the existence of an excitation-number staircase in laser excitation of atomic ensembles into Rydberg states. It is shown that such ordered states can be selectively excited by chirped laser pulses, and, via quantum state transfer from atoms to light, be used to create crystalline photonic states.
我们描述了一种在扩展的里德堡原子系综中控制多体状态的方法，即在冷冻原子气体的激光激发过程中形成晶体结构。具体来说，我们预测了在激光激发原子系综进入里德堡态时存在激发数阶梯的现象。结果表明，通过啁啾激光脉冲可以选择性地激发这种有序状态，并通过原子到光的量子态转移，用于创建晶体光子态。
