Polariton-Assisted Inelastic Tunneling through a Quantum Well
Théophile Seck, Yanko Todorov, Guido Pupillo +1
We investigate electronic transport through a doped quantum well strongly interacting with a photonic mode confined in a double-metal cavity. Using a nonequilibrium Green's functio…
Microscopic quantum description of surface plasmon polaritons: Revealing intrinsic ultrastrong light-matter coupling
Florian Maurer, Thomas F. Allard, Yanko Todorov +2
We develop a microscopic quantum theory of surface plasmon polaritons valid for arbitrary metal-dielectric geometries. Our framework is based on the Power-Zienau-Woolley representa…
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…
Multimode Phonon-Polaritons in Lead-Halide Perovskites in the Ultrastrong Coupling Regime
Dasom Kim, Jin Hou, Geon Lee +14
Phonons play a central role in fundamental solid-state phenomena, including superconductivity, Raman scattering, and symmetry-breaking phases. Harnessing phonons to control these e…
