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

BACKGROUND One of the most important phenomena in cavity quantum electrodynamics
(cQED) is the so-called strong coupling regime, which appears when the interaction …

Over the past decade, the possibility of manipulating chemistry and material properties using
hybrid light–matter states has stimulated considerable interest. Hybrid light–matter states …

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 …

Ultrastrong coupling between light and matter has, in the past decade, transitioned from a
theoretical idea to an experimental reality. It is a new regime of quantum light–matter …

Recent experiments demonstrate the control of chemical reactivities by coupling molecules
inside an optical microcavity. In contrast, transition state theory predicts no change of the …

Molecular polaritons are the optical excitations which emerge when molecular transitions
interact strongly with confined electromagnetic fields. Increasing interest in the hybrid …

Interactions between light and matter play an instrumental role in spectroscopy, sensing,
quantum information processing and lasers. In most of these applications, light is considered …

It is possible to modify the chemical and physical properties of molecules, not only through
chemical modifications but also by coupling molecules strongly to light. More intriguingly …

Many chemical methods have been developed to favor a particular product in
transformations of compounds that have two or more reactive sites. We explored a different …
