本文从理论上探讨了具有较弱非线性的谐振腔几何阻挫晶格的驱动耗散物理，光子-光子相互作用小于损失率。在这样的系统中，由于干涉效应，在暗点处概率为零的光子模式存在于单粒子水平。特别是，我们研究了一个细胞的行为与三个耦合谐振器以及扩展的Lieb晶格在一个和两个维度。通过考虑部分泵浦方案，与驱动场不适用于暗网站，我们预测，即使在相对较弱的光子-光子相互作用的存在下，名义上的暗网站实现了有限的光子人口与强相关性。我们表明，这是一个后果的双光子和多光子状态，在没有挫折将是不可见的观测。
We explore theoretically the driven-dissipative physics of geometrically frustrated lattices of cavity resonators with relatively weak nonlinearities, i.e., a photon-photon interaction smaller than the loss rate. In such systems, photon modes with zero probability at dark sites are present at the single-particle level due to interference effects. In particular, we study the behavior of a cell with three coupled resonators as well as extended Lieb lattices in one and two dimensions. By considering a partial pumping scheme, with the driving field not applied to the dark sites, we predict that even in the presence of relatively weak photon-photon interactions the nominally dark sites achieve a finite photonic population with strong correlations. We show that this is a consequence of biphoton and multiphoton states that in the absence of frustration would not be visible in the observables.
