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…

Cavity-Mediated Coupling between Local and Nonlocal Modes in Landau Polaritons
Sae R. Endo, Dasom Kim, Shuang Liang +8
The multimode ultrastrong coupling (USC) regime has emerged as a novel platform for accessing previously inaccessible phenomena in cavity quantum electrodynamics. Of particular int…
