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…
On-demand steering of hyperbolic chiral polaritons
Andrea S. Dai, Fuyang Tay, Ding Xu +11
Control of light polarization and propagation in sub-wavelength architectures is foundational to nanophotonic technologies. A frontier direction is to leverage strong optical spin-…
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…
