论文摘要
我们首先使用量子方法来复制单个原子放松的众所周知的结果，同时证明了它为耗散动力学提供的直观图片。通过使用单个“量子轨迹”，该方法允许模拟整体处理无法访问的系统。通过复制共振荧光来显示这一点，使我们能够同时证明该方法通过创建离散光子流来促进计算光子统计。为了分析这些分析，我们巩固了一种计算二阶相干函数的计算方法的理论基础和实施。然后，开发了通过量子跳跃方法进行建模的两种原子系统来建模的过程。在研究与耗散性和相干相互作用的状态脱钩之前，我们证明了导致大大修饰的发射光谱的合作效应。在这里，我们发现了量子跳跃方法提供的新型见解，并提供了开始研究宏观跳跃发生的工具，并在两个两级偶极 - 偶极 - 偶极偶联原子的系统中形成了宏观黑暗时期。
We first use the quantum method to replicate the well-known results of a single atom relaxing, whilst demonstrating the intuitive picture it provides for dissipative dynamics. By use of individual "quantum trajectories", the method allows for simulation of systems inaccessible to ensemble treatments. This is shown by replicating resonance fluorescence, allowing us to concurrently demonstrate the method's facilitation of calculating photon statistics by the creation of discrete photon streams. To analyse these, we solidify the theoretical basis for, and implement, a computational method of calculating second-order coherence functions. A process by which to model interacting two-atom systems to allow for computation with the quantum jump method is then developed. Using this, we demonstrate cooperative effects leading to greatly modified emission spectra, before investigating the decoupling of states from dissipative and coherent interactions. Here, we find the novel insight provided by the quantum jump method both births and provides the tools with which to begin an investigation into the occurrence of macroscopic jumps and the formation of macroscopic dark periods in a system of two two-level dipole-dipole coupled atoms.
