研究了弛豫条件下强相互作用原子里德堡态的共振光激发。我们利用量子随机(蒙特卡罗)波函数模拟了二维晶格中数十个原子的耗散动力学。我们证明了在典型的实验条件下，在几个μS的时间尺度上，涉及到原子相干性的缓慢里德堡态衰变和相当大的驰豫，原子系综趋近于一个稳态态，其中原子之间的大部分量子关联已经衰变。然而，稳态表现出里德堡激发几率的很强的经典关联。
We study resonant optical excitations of strongly interacting Rydberg states of atoms in the presence of relaxations. We employ the quantum stochastic (Monte Carlo) wavefunctions to simulate the dissipative dynamics of tens of atoms in two-dimensional lattices. We show that under typical experimental conditions involving the slow Rydberg state decay and sizable relaxation of atomic coherences, on the timescale of several μs the atomic ensemble approaches a stationary state in which much of the quantum correlations between the atoms have decayed away. The steady state, however, exhibits strong classical correlations of Rydberg excitation probabilities.
