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…
Vacuum-dressed superconductivity in NbN observed in a high- terahertz cavity
Hongjing Xu, Andrey Baydin, Qinyan Yi +8
Emerging theoretical frameworks suggest that physical properties of matter can be altered within an optical cavity by harnessing quantum vacuum electromagnetic fluctuations, even i…
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…
Realization of a Chiral Photonic-Crystal Cavity with Broken Time-Reversal Symmetry
Kiran M. Kulkarni, Hongjing Xu, Fuyang Tay +7
Light-matter interactions in chiral cavities offer a compelling route to manipulate material properties by breaking fundamental symmetries such as time-reversal symmetry. However,…
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…
