Phase transitions to quantum condensed phases—such as Bose–Einstein condensation
(BEC), superfluidity, and superconductivity—have long fascinated scientists, as they bring …

From a theoretical point of view, we discuss a variety of phenomena linked to the spin and
polarization degree of freedom of exciton-polaritons in semiconductor microcavities. We start …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

The Dicke model describes the coupling between a quantized cavity field and a large
ensemble of two‐level atoms. When the number of atoms tends to infinity, this model can …

Semiconductor microcavities, in which strong coupling of excitons to confined photon modes
leads to the formation of exciton–polariton modes, have increasingly become a focus for the …

We study a disordered ensemble of quantum emitters collectively coupled to a lossless
cavity mode. The latter is found to modify the localization properties of the “dark” eigenstates …

We study spontaneous quantum coherence in an out of an equilibrium system, coupled to
multiple baths describing pum** and decay. For a range of parameters describing …

Exciton–polaritons in a microcavity are composite two-dimensional bosonic quasiparticles,
arising from the strong coupling between confined light modes in a resonant planar optical …

Large arrowhead matrices with randomly distributed entries describe a variety of important
phenomena where a degree of freedom is nonlocally coupled to a disordered continuum of …

Although only a handful of organic materials have shown polariton condensation, their study
is rapidly becoming more accessible. The spontaneous appearance of long-range spatial …
