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…
