讲座内容：

Superradiance is essentially a case of correlated dissipation leading to the macroscopic quantum coherence, while the so-called Subradiance and its realization is more challenging than superradiance due to the need to suppress various decay channels, though it holds significant potential for quantum information applications. In this talk, I will first address the superradiance properties of plasmonic waveguides and dielectric photonic crystals, and demonstrate their potential to support near-ideal superradiance across expanded spatial domains. Then, I’ll introduce a theoretical framework that addresses the challenges of achieving subradiance in quantum systems, which reveals particularly the dynamics of single-excitation processes in complex systems, facilitating the prediction of subradiance dynamics for long-lived multipartite entanglement without the need for intricate integral computations. Finally, an outlook for exploring potential applications in fermionic systems is also briefed.
