Close Encounters between Periodic Light and Periodic Arrays of Quantum Emitters
Frieder Lindel · Carlos J. Sánchez Martínez · Johannes Feist · Francisco J. García-Vidal
Abstract
Author(s): Frieder Lindel, Carlos J. Sánchez Martínez, Johannes Feist, and Francisco J. García-Vidal<br/><p>We introduce crystal polaritons, hybrid excitations formed when the collective excitations of a periodic quantum-emitter array strongly couple to the resonant Bloch modes of a metasurface. This realizes a cavity-QED platform in which periodic light and periodic matter are treated on the same footing…</p><br/>[Phys. Rev. Lett. 137, 103802] Published Wed Sep 02, 2026
