Symmetry-Controlled Ultrastrong Phonon-Photon Coupling in a Terahertz Cavity
Dasom Kim, Maxime Dherbécourt, Sae R. Endo +8
Optical cavities provide a powerful means to engineer light-matter hybrid states by coupling confined electromagnetic fields with matter excitations. Achieving in situ control of t…

Enhancement of the electron-phonon scattering induced by intrinsic surface plasmon-phonon polaritons
David Hagenmüller, Johannes Schachenmayer, Cyriaque Genet +2
We investigate light-matter coupling in metallic crystals where plasmons coexist with phonons exhibiting large oscillator strength. We demonstrate theoretically that this coexisten…
