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…

Quantum Light Nano-Imaging

Michael Dapolito, Matthew Fu, Fuyang Tay +20

Entanglement and quantum correlations are central to the physics of quantum materials, yet they have remained notoriously difficult to access experimentally. Accessing these phenom…

Chip-Scale Aligned Chiral Carbon Nanotubes Exhibiting Giant Second Harmonic Generation

Rui Xu, Jacques Doumani, Viktor Labuntsov +16

Chiral carbon nanotubes (CNTs) are direct-gap semiconductors with optical properties governed by one-dimensional excitons with enormous oscillator strengths. Each species of chiral…

Floquet Engineering of a Quasiequilibrium Superradiant Phase Transition in Landau Polaritons

Wen-Hua Wu, Fuyang Tay, Mengqian Che +3

Superradiant phase transitions (SRPTs), characterized by photon condensation and macroscopic matter polarization, are forbidden in equilibrium for homogeneous fields by no-go theor…

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…
