Impact of Multiple Environments on Two-Photon Emission in a Semiconductor Model via Lindblad Dynamics

Many-body interactions play a crucial role in shaping the properties of doped two-dimensional materials. In particular, the unique optical and electronic characteristics of transition metal dichalcogenides (TMDs) make them promising for applications in electronics and optoelectronics. In this work, we investigate two-photon emission from a three-level excitonic system embedded in multiple environments. Using the Lindblad equation, we describe the interplay between excitonic states and their surrounding environments—photons, phonons, and more. We analyze how relaxation and dephasing effects, driven by these couplings, influence the interferometric properties of direct two-photon emission from the excitonic system.
