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 …

An important goal of modern condensed-matter physics involves the search for states of
matter with emergent properties and desirable functionalities. Although the tools for material …

Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

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

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 …

Colloidal metal‐halide perovskite nanocrystals (MHP NCs) are gaining significant attention
for a wide range of optoelectronics applications owing to their exciting properties, such as …

Polaritons are a hybrid class of quasiparticles originating from the strong and resonant
coupling between light and matter excitations. Recent years have witnessed a surge of …

Moiré superlattices have emerged as a new platform for studying strongly correlated
quantum phenomena, but these systems have been largely limited to van der Waals layer …

Polaritons, originating from the interactions between photons and material excitations, have
attracted attention because of their strong field compression and deeply subdiffractional …
