论文摘要
集体排放行为通常由完全对称的迪克状态的衰减动力学描述。为了研究更现实的情况，我们研究了替代的初始状态，诱导了更复杂的时间演变。将完全倒置的dicke状态和具有不平等重量的DICKE基态的叠加状态作为例子以及与簇中原子的超高为示例，并以多个波长分隔为单位。蒙特卡洛波函数方法是研究量子状态动力学的框架，量子状态的动力学一方面由量子跳跃确定，另一方面是连续的演化动力学。我们将此方法与为密度矩阵的对角线成分编写的速率方程式系统的经典图片进行了比较。
Collective emission behavior is usually described by the decay dynamics of the completely symmetric Dicke states. To study a more realistic scenario, we investigate alternative initial states inducing a more complex time evolution. Superposition states of the fully inverted Dicke state and the Dicke ground state with unequal mutual weights are studied as examples as well as superradiance stemming from atoms in clusters separated by more than one wavelength. The Monte Carlo wave function method serves as framework to study the dynamics of quantum states, which is determined by quantum jumps on the one hand and continuous evolution dynamics on the other hand. We compare this method with the classical picture of a system of rate equations written for the diagonal components of the density matrix.
