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 …

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 …

This Perspective provides a brief introduction into the theoretical complexity of polaritonic
chemistry, which emerges from the hybrid nature of strongly coupled light–matter states. To …

Coupling between molecules and vacuum photon fields inside an optical cavity has proven
to be an effective way to engineer molecular properties, in particular reactivity. To ease the …

Polariton chemistry exploits the strong interaction between quantized excitations in
molecules and quantized photon states in optical cavities to affect chemical reactivity …

The electron attachment variant of equation-of-motion coupled-cluster theory (EOM-EA-CC)
is generalized to the case of strong light–matter coupling within the framework of cavity …

Recent experimental advances enable the manipulation of quantum matter by exploiting the
quantum nature of light. However, paradigmatic exactly solvable models, such as the Dicke …

Cavity modification of material properties and phenomena is a novel research field largely
motivated by the advances in strong light-matter interactions. Despite this progress, exact …

We provide a simple and intuitive theory to explain how coupling a molecule to an optical
cavity can modify ground-state chemical reactivity by exploiting intrinsic quantum behaviors …

We present the theoretical derivation and numerical implementation of the linear response
equations for relativistic quantum electrodynamical density functional theory (QEDFT). In …
