Lee H, Whetten B, Kim B, Woo J, Koo Y, Bae J, et al.
Phys Rev Lett . 2024 Apr; 132(13):133001. PMID: 38613300
Exciton-polaritons confined in plasmonic cavities are hybridized light-matter quasiparticles, with distinct optical characteristics compared to plasmons and excitons alone. Here, we demonstrate the electric tunability of a single polaritonic quantum...
