非对称泵浦耦合二能级系统的共振荧光
Resonance fluorescence of two asymmetrically pumped and coupled two-level systems
摘要：
我们用开放量子系统的方法研究了一对原子或（更一般地）亚原子的驱动耗散二能级系统。允许设置中的复值耦合，这是一个连贯的和不连贯的字符，产生了一个不同的耦合景观。我们考虑这个景观上的几个点，例如，在两个耦合的二能级系统之间的耦合是由相干，非相干，不对称，甚至单向的相互作用。穿越耦合地形导致显着的特点，人口对，相关性和光谱。最值得注意的是，著名的单个原子的莫洛三重态光谱可能被莫洛五重态（甚至是光谱单线态）取代，这种设置允许出现布居捕获，所有这些都取决于两能级系统之间耦合的精确性质。
英文摘要：
We study a driven-dissipative duo of two-level systems in an open quantum systems approach, modelling a pair of atoms or (more generally) meta-atoms. Allowing for complex-valued couplings in the setup, which are of both a coherent and incoherent character, gives rise to a diverse coupling landscape. We consider several points on this landscape, for example where the coupling between the two coupled two-level systems is dominated by coherent, incoherent, unsymmetrical and even unidirectional interactions. Traversing the coupling terrain leads to remarkable features in the populations of the pair, correlations and optical spectra. Most notably, the famous Mollow triplet spectrum for a single atom may be superseded for a pair by a Mollow quintuplet (or even by a spectral singlet) and the setup allows for population trapping to arise, all depending upon the precise nature of the coupling between the two-level systems.
