标题： No oscillating subradiant correlations in a strongly driven quantum emitter array

摘要： 我们理论研究强驱动的$N$两能级原子阵列中随时间变化的相关性，这些原子与波导中的光子耦合。 我们关注李普诺夫超算符$\{\lambda\}$的谱，该谱决定了相关性衰减率$-\Re \lambda$和频率$\Im\lambda$。 我们的主要发现是通过振幅为$\Omega$的强相干驱动，抑制了原子态之间的亚辐射振荡关联：$|\Re \lambda|\ge m\gamma/2$，其中$\gamma$是单原子自发衰减率，$m=|\Im \lambda/(2\Omega)|$是一个非零整数，用于描述随时间振荡的关联$\propto \exp(\pm 2i m|\Omega| t)$。 此极限与原子数量$N$无关；它既适用于小阵列，也适用于宏观极限。 我们通过数值模拟展示了亚辐射的抑制，并基于使用单纯复形和偏序集的谱理论对李雅普诺夫算子的解析分解，提供了严格的证明。 显示英文摘要

摘要： We theoretically study time-dependent correlations in a strongly driven array of $N$ two-level atoms, coupled to photons in a waveguide. We focus on the spectrum $\{\lambda\}$ of the Liouvillian superoperator, which determines the correlation decay rates $-\Re \lambda$ and the frequencies $\Im\lambda$. Our main finding is the suppression of subradiant oscillating correlations between atomic states by a strong coherent drive of amplitude $\Omega$: $|\Re \lambda|\ge m\gamma/2$, where $\gamma$ is the single-atom spontaneous decay rate and $m=|\Im \lambda/(2\Omega)|$ is a nonzero integer for correlations oscillating in time $\propto \exp(\pm 2i m|\Omega| t)$. This limit is independent of the number of atoms $N$; it holds both for small arrays and in the macroscopic limit. We demonstrate the suppression of subradiance numerically and provide a rigorous proof based on the analytical decomposition of the Liouvillian using spectral theory of simplicial complexes and posets.
