New experimental platforms that exhibit non-Markovian (nM) behavior—such as slow-light waveguides and long-range quantum networks—have shown promising applications in quantum information and technologies [1,2]. However, we still lack comprehensive theoretical tools to understand such systems. In this work [3], we develop a model to study a variety of waveguides in the nM regime. We show how the model leads to a set of delayed differential equations that can be solved numerically, allowing for the simulation of arrays of multiple emitters with high precision. This opens the door to unexplored physics. We use these equations to investigate the emergence of superradiance in the nM limit, as well as the variation in the system’s decay rate.
