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…

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,…
