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 …

Chemical manifestations of strong light–matter coupling have recently been a subject of
intense experimental and theoretical studies. Here we review the present status of this field …

Polaritonic chemistry exploits strong light–matter coupling between molecules and confined
electromagnetic field modes to enable new chemical reactivities. In systems displaying this …

The field of particle physics is at the crossroads. The discovery of a Higgs-like boson
completed the Standard Model (SM), but the lacking observation of convincing resonances …

Exciton-polaritons provide a versatile platform for investigating quantum electrodynamics
effects in chemical systems, such as polariton-altered chemical reactivity. However, using …

Plasmonic nanocavities enable the confinement of molecules and electromagnetic fields
within nanometric volumes. As a consequence, the molecules experience a remarkably …

A material with symmetry breaking inside can transmit the symmetry breaking to its vicinity
by vacuum electromagnetic fluctuations. Here, we show that vacuum quantum fluctuations …

Collectively coupling molecular ensembles to a cavity has been demonstrated to modify
chemical reactions akin to catalysis. Theoretically understanding this experimental finding …

Light–matter interaction not only plays an instrumental role in characterizing materials'
properties via various spectroscopic techniques but also provides a general strategy to …
