When molecules are coupled to an optical cavity, new light–matter hybrid states, so-called
polaritons, are formed due to quantum light–matter interactions. With the experimental …

The interaction between molecular electronic transitions and electromagnetic fields can be
enlarged to the point where distinct hybrid light–matter states, polaritons, emerge. The …

In this review, we present the theoretical foundations and first-principles frameworks to
describe quantum matter within quantum electrodynamics (QED) in the low-energy regime …

Picocavities are sub-nanometer-scale optical cavities recently found to trap light, which are
formed by single-atom defects on metallic facets. Here, we develop simple picocavity …

The fundamental understanding of molecular quantum electrodynamics via the strong light–
matter interactions between a nanophotonic cavity and quantum emitters opens various …

We present a mixed quantum-classical simulation of polariton dynamics for molecule–cavity
hybrid systems. In particular, we treat the coupled electronic–photonic degrees of freedom …

In this tutorial review, we briefly discuss the role that the Jaynes–Cummings model occupies
in present-day research in cavity quantum electrodynamics with a particular focus on the so …

We develop a theoretical framework for describing light-matter interactions in cavity quantum
electrodynamics (QED), optimized for efficient convergence at arbitrarily strong coupling …

We address the fundamental question of whether or not it is possible to achieve conditions
under which the coupling of a single dipole to a strongly confined electromagnetic vacuum …

Strong coupling between metal nanoparticles and molecules mixes their excitations,
creating new eigenstates with modified properties such as altered chemical reactivity …
