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…
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…
Quantum Vacuum in Matter
Andrey Baydin, Hanyu Zhu, Motoaki Bamba +2
An intriguing consequence of quantum field theory is that vacuum is not empty space; it is full of quantum fluctuating electromagnetic fields, or virtual photons, corresponding to…
Zeeman polaritons as a platform for probing Dicke physics in condensed matter
T. Elijah Kritzell, Jacques Doumani, Tobias Asano +11
The interaction of an ensemble of two-level atoms and a quantized electromagnetic field, described by the Dicke Hamiltonian, is an extensively studied problem in quantum optics. Ho…
Multimode Ultrastrong Coupling in Three-Dimensional Photonic-Crystal Cavities
Fuyang Tay, Ali Mojibpour, Stephen Sanders +8
Recent theoretical studies have highlighted the role of spatially varying cavity electromagnetic fields in exploring novel cavity quantum electrodynamics (cQED) phenomena, such as…
