我们描述了一种控制里德伯原子扩展系综中的多体态的方法，在激光激发冷冻原子气体期间形成晶体结构。具体来说，我们预测在激光激发原子系综进入里德堡态时存在激发数阶梯。研究表明，这种有序态可以通过啁啾激光脉冲选择性地激发，并通过从原子到光的量子态转移，用于创建晶体光子态。
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.
