Nonlinear Diamagnetic Interactions in Ultrastrongly Coupled 2D Electrons

Dasom Kim, Kiran M. Kulkarni, Vaibhav Sharma +15

The quantum Hopfield model is widely used to describe ultrastrong light--matter coupling between cavity photons and collective bosonic excitations in solids, where the diamagnetic…

Dicke materials as a resource for quantum squeezing

Vaibhav Sharma, Shung-An Koh, Jonathan Stepp +8

We study magnetic materials whose low energy physics can be effectively described by a Dicke model, which we term Dicke materials. We show how a Dicke model emerges in such materia…

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…

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…

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…
