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…

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…

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,…
