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 …

Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

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 …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

The prospect of controlling the electronic properties of materials via the vacuum fields of
cavity electromagnetic resonators is emerging as one of the frontiers of condensed matter …

In the regime of deep strong light–matter coupling, the coupling strength exceeds the
transition energies of the material,–, fundamentally changing its properties,; for example, the …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

Exciton transport can be enhanced in the strong coupling regime where excitons hybridize
with confined light modes to form polaritons. Because polaritons have group velocity, their …

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 …
