标题： Exact solution for the collective non-Markovian decay of two fully excited quantum emitters

摘要： 波导量子电动力学构成了光与物质相互作用的现代范式，在这种范式中，强耦合、环境结构和传播延迟可以打破量子发射器在自由空间中通常遇到的辐射条件。 这些特性将量子发射器的激发与受约束的辐射模式交织在一起，形成复杂的多光子动力学。 到目前为止，将发射器的集体衰减与由模式引起的非马尔可夫效应结合起来，尚未得到完整的解决方案，这些系统背后的详细物理机制仍然未知。 在这里，我们分析了一个由两个激发发射器耦合到一维单带波导的最小系统中的集体非马尔可夫衰减。 我们开发了一种用初等函数表示的精确解，揭示了隐藏的对称性并预测了新的自发衰减形式。 这种依赖于真空耦合和远离带中心的失谐的集体非马尔可夫动力学表现出奇特的特征，可以用一个简单且易于获得的标准来表征。 我们的解析方法揭示了集体光-物质相互作用的复杂性，并为理解多粒子开放量子系统开辟了一条路径。 显示英文摘要

摘要： Waveguide quantum electrodynamics constitutes a modern paradigm for the interaction of light and matter, in which strong coupling, bath structure, and propagation delays can break the radiative conditions that quantum emitters typically encounter in free space. These characteristics intertwine the excitations of quantum emitters and guided radiation modes to form complex multiphoton dynamics. So far, combining the collective decay of the emitters with the non-Markovian effects induced by the modes has escaped a full solution and the detailed physics behind these systems remains unknown. Here we analyze such a collective non-Markovian decay in a minimal system of two excited emitters coupled to a one-dimensional single-band waveguide. We develop an exact solution for this system in terms of elementary functions that unveils hidden symmetries and predicts new forms of spontaneous decay. The collective non-Markovian dynamics, which are strongly dependent on the vacuum coupling and the detuning from the center of the band, show exotic features that can be characterized with a simple and readily available criterion. Our analytic methods shed light on the complexity of collective light-matter interactions and open up a pathway for understanding multiparticle open quantum systems.
