Atomically thin transition metal dichalcogenides (TMDs) are 2D semiconductors with tightly
bound excitons and correspondingly strong light–matter interactions. Owing to the weak van …

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 …

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

Molecular polaritons are quasiparticles resulting from the hybridization between molecular
and photonic modes. These composite entities, bearing characteristics inherited from both …

Twisted van der Waals heterostructures have latterly received prominent attention for their
many remarkable experimental properties and the promise that they hold for realizing …

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 …

The emergent field of cavity quantum materials bridges collective many-body phenomena in
solid state platforms with strong light–matter coupling in cavity quantum electrodynamics …

Transport of excitons and charge carriers in molecular systems can be enhanced by
coherent coupling to photons, giving rise to the formation of hybrid excitations known as …

Placing quantum materials into optical cavities provides a unique platform for controlling
quantum cooperative properties of matter, by both weak and strong light–matter coupling …

The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …
