论文摘要
我们研究了两个耦合两级系统的典型模型,其中相干和耗散耦合之间的竞争产生了丰富的现象学。特别是,我们分析了不对称耦合的情况,以及手性(或单向)耦合的限制情况。我们研究了系统的各种量子光学特性,包括其稳态种群,功率谱和二阶相关函数,并概述了每个数量中出现的特征特征,因为一个人通过有效的复杂耦合的非平凡景观进行了扫描。最重要的是,我们揭示了人口捕获,意外光谱特征和强烈的光子相关的实例。
We study a prototypical model of two coupled two-level systems, where the competition between coherent and dissipative coupling gives rise to a rich phenomenology. In particular, we analyze the case of asymmetric coupling, as well as the limiting case of chiral (or one-way) coupling. We investigate various quantum optical properties of the system, including its steady state populations, power spectrum, and second-order correlation functions, and outline the characteristic features which emerge in each quantity as one sweeps through the nontrivial landscape of effective complex couplings. Most importantly, we reveal instances of population trapping, unexpected spectral features and strong photon correlations.
