Photonic synthetic materials provide an opportunity to explore the role of microscopic
quantum phenomena in determining macroscopic material properties. There are, however …

We overview the concept of dynamical phase transitions (DPTs) in isolated quantum
systems quenched out of equilibrium. We focus on non-equilibrium transitions characterized …

Interactions between atoms and light in optical cavities provide a means of investigating
collective (many-body) quantum physics in controlled environments. Such ensembles of …

We report on the engineering of a nondispersive (flat) energy band in a geometrically
frustrated lattice of micropillar optical cavities. By taking advantage of the non-Hermitian …

We review the unconventional photon blockade mechanism. This quantum effect remarkably
enables a strongly sub-Poissonian light statistics, even from a system characterized by a …

Enhancing optical nonlinearities so that they become appreciable on the single photon level
and lead to nonclassical light fields has been a central objective in quantum optics for many …

Molecular polaritons are quasiparticles resulting from the hybridization between molecular
and photonic modes. These composite entities, bearing characteristics inherited from both …

Chirality is an asymmetric property widely found in nature. Here, we propose and
demonstrate experimentally the spontaneous emergence of chirality in an on-chip ultrahigh …

We use coupled micropillars etched out of a semiconductor microcavity to engineer a spin-
orbit Hamiltonian for photons and polaritons in a microstructure. The coupling between the …

Multi-cavity photonic systems, also known as photonic molecules, exhibit multi-well
potentials that may prove useful for advanced quantum and nonlinear optics,,,. A key …
