Metasurfaces are 2D artificial materials consisting of arrays of metamolecules, which are
exquisitely designed to manipulate light in terms of amplitude, phase, and polarization state …

Recent experiments have demonstrated that light and matter can mix together to an extreme
degree, and previously uncharted regimes of light-matter interactions are currently being …

An optimal single-photon source should deterministically deliver one, and only one, photon
at a time, with no trade-off between the source's efficiency and the photon …

We demonstrate the emergence of nonreciprocal superradiant phase transitions and novel
multicriticality in a cavity quantum electrodynamics system, where a two-level atom interacts …

Photonic nanostructures provide a means of tailoring the interaction between light and
matter and the past decade has witnessed tremendous experimental and theoretical …

Topological features—global properties not discernible locally—emerge in systems ranging
from liquid crystals to magnets to fractional quantum Hall systems. A deeper understanding …

This is a review on theoretical and experimental studies on dielectric microcavities, which
play a significant role in fundamental and applied research. The basic concepts and theories …

Coherent coupling between plasmons and transition dipole moments in emitters can lead to
two distinct spectral effects: vacuum Rabi splitting at strong coupling strengths, and induced …

The law of momentum conservation rules out many desired processes in optical
microresonators. We report broadband momentum transformations of light in asymmetric …

Phenomena associated with the topological properties of physical systems can be naturally
robust against perturbations. This robustness is exemplified by quantized conductance and …
