Tuning Exciton-Polariton Transport in Optical Cavity

Exciton-polariton is a promising light-matter hybrid system, formed by coupling matter excitation with microcavity optical photons, that has been shown to exhibit coherent transport of information and particles. This coupling can provide long-distance coherent propagation of both photon and exciton with proposed applications for energy transport and quantum information science. In this work, we develop a new quantum dynamics approach to gain microscopic insights, enabling us to modify the dynamics of both photons and excitons. Specifically, we study exciton-polaritons in multilayered materials, following previous works [Nano Lett 23.9 (2023): 4082-4089, and Nat. Commun 14.1 (2023): 3881]. We show that adjusting the geometrical parameters of this multi-layered system leads to non-trivial modifications of exciton-polariton transport.
