Chiral Vacuum Engineering of Quantum Hall Matter
Kiran M. Kulkarni, Andrey Baydin, Motoaki Bamba +3
We reveal that a chiral cavity distinguishes the resonant and antiresonant interactions between a two-dimensional electron gas and the cavity vacuum. For co-rotating helicities, th…
Generalized Foldy-Wouthuysen approach for the derivation of non-relativistic effective field theories
Tobias Asano, Fabio Di Pumpo, Enno Giese +1
Effective field theories (EFTs) are a powerful framework for performing high-precision calculations at reduced complexity compared to their fundamental counterparts. A particularly…
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…
Observation of cooperative strong coupling between optical phonon and crystal-field excitations in a pseudo Jahn-Teller system
Fangliang Wu, Xiaoxuan Ma, Zhongwei Zhang +6
Cooperative interactions between localized electronic excitations and crystal lattice are central to the emergence of complex structural phases in materials. However, the scaling r…
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…
