Tunable exciton polaritons in biased bilayer graphene
Exciton polaritons---hybrids of light and matter---unlock fascinating quantum effects, from sensing and efficient lasers to quantum memories. Here, the authors show how placing electrically biased bilayer graphene inside an optical cavity creates a highly tunable playground for strong light-matter interactions. The theoretical analysis highlights how exciton lifetimes and epsilon-near-zero materials play a key role in boosting exciton-photon coupling. This platform's flexibility allows precise control over both the polariton energy landscape and the strength of light-matter mixing (Rabi splitting), pushing the system into the strong coupling regime.
