论文摘要
确定性产生多X含量次级国家被证明是具有挑战性的。在这里，我们基于原子集合的不连贯的驱动，在有限大小的偶极偶联量量量量发射器的有限大小有序阵列中提出了一条可行的途径。特别是，我们表明，如果最初只有一半的原子被激发，则可以达到与长寿命的次化状态的最大耦合。我们通过计算发射光的动态荧光光谱来表征所得状态的性质。最后，我们阐明了在足够致密的原子阵列的衰减过程中相干相互作用的作用，从而导致相干驱动的辐射爆发，从而导致随后降低了制备多XCITITION次级次级态状态的机会。
The deterministic generation of multiexcitation subradiant states proves to be challenging. Here, we present a viable path towards their transient generation in finite-sized ordered arrays of dipole-dipole coupled quantum emitters, based on incoherent driving of the atomic ensemble. In particular, we show that a maximal coupling to long-lived subradiant states is achieved if only half of the atoms are initially excited. We characterize the nature of the resulting states by calculating the dynamic fluorescence spectrum of the emitted light. Finally, we elucidate the role of coherent interactions during the decay process of sufficiently dense atomic arrays, which result in a coherently driven radiation burst that leads to a subsequent reduction of the chances to prepare multiexcitation subradiant states.
