After resuming the basic facts about Bose–Einstein condensation of weakly interacting
systems, we review the main experimental and theoretical works aimed at the realization of …

This thesis presents a theoretical description of the phase transition, with formation of long-
range spatial coherence, occurring in a gas of exciton-polaritons in a semiconductor …

We consider a generalization of the Dicke model. This model describes localized, physically
separated, saturable excitations, such as excitons bound on impurities, coupled to a single …

The experimental realization of Bose-Einstein condensation (BEC) with atoms and
quasiparticles has triggered wide exploration of macroscopic quantum effects. Microcavity …

The strong coupling of light and excitons in a two-dimensional semiconductor microcavity
results in a new eigenstate of quasiparticles called polaritons. Microcavity polaritons have …

In the past decade, a two-dimensional matter-light system called the microcavity exciton-
polariton has emerged as a new promising candidate of Bose-Einstein condensation (BEC) …

In this review, we present a comprehensive set of experimental results on microcavity-
polariton Bose-Einstein Condensation (BEC), obtained within a close collaboration between …

Strong light–matter coupling has given rise to fascinating phenomena and observations in
the past decades. The emergence of the field of polaritonics has been particularly evidenced …

Recent experiments have shown several effects indicative of Bose-Einstein condensation in
polaritons in GaAs-based microcavity structures when a harmonic potential trap for the two …

Recent experiments have shown that it is possible to create an in-plane harmonic potential
trap for a two-dimensional (2D) gas of exciton polaritons in a microcavity structure, and …
