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 …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

In quantum electrodynamics, the choice of gauge influences the form of light–matter
interactions. However, gauge invariance implies that all physical results should be …

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 …

Exciton-polaritons are bosonic quasiparticles that arise from the normal mode splitting of
photons in a microcavity and excitons in a semiconductor material. One of the most …

A two-level system resonantly interacting with an ac magnetic or electric field constitutes the
physical basis of diverse phenomena and technologies. However, Schrödinger's equation …

We show how analogs of a large number of well-known nonlinear-optics phenomena can be
realized with one or more two-level atoms coupled to one or more resonator modes …

Non-perturbative coupling of photons and excitons produces hybrid particles, exciton–
polaritons, which have exhibited a variety of many-body phenomena in various microcavity …

We present a new theoretical framework, polarized Fock states (PFSs), to describe the
coupled molecule–cavity hybrid system in quantum electrodynamics. Through the quantum …

Recent advancements on the fabrication of organic micro-and nanostructures have
permitted the strong collective light–matter coupling regime to be reached with molecular …
