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 …

We develop a microscopic theory for the multimode polariton dispersion in materials
coupled to cavity radiation modes. Starting from a microscopic light–matter Hamiltonian, we …

We demonstrate polariton lasing in a bulk ZnO planar microcavity under non-resonant
optical pumping at a small negative detuning (δ∼− 1/6 the 130 meV vacuum Rabi splitting) …

A metamaterial perfect absorber based on layered, doped and undoped semiconductors is
experimentally and theoretically investigated. Design rules are given to control the …

Half‐light and half‐matter exciton polaritons have demonstrated profound impacts on
coherent quantum phenomena. Two‐dimensional (2D) organic− inorganic perovskite …

We review the recent developments of the polariton physics in microcavities featuring the
exciton–photon strong coupling at room temperature, and leading to the achievement of …

A ZnO planar optical microcavity displaying room-temperature polariton lasing over a wide
range of cavity-exciton detunings has been fabricated. The cavity combines optimum …

Periodic incorporation of quantum wells inside a one-dimensional Bragg structure is shown
to enhance coherent coupling of excitons to the electromagnetic Bloch waves. We …

We realize a Fabry-Perot hybrid microcavity containing an association of a ZnO thin layer
and of a layer of the two-dimensional layered perovskite 5-methyl-2-furanmethanamonium …

We address the problem of the correct description of light-matter coupling for excitons and
cavity photons in the case of systems with multiple photon modes or excitons, respectively …
