Recently a new type of system exhibiting spontaneous coherence has emerged—the
exciton–polariton condensate. Exciton–polaritons (or polaritons for short) are bosonic …

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 …

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

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 …

Abstract Cavity exciton-polaritons,(polaritons) are bosonic quasi-particles offering a unique
solid-state system for investigating interacting condensates,,,,,,,. Up to now, disorder-induced …

We explore the nature of the Bose condensation transition in driven open quantum systems,
such as exciton-polariton condensates. Using a functional renormalization group approach …

Polariton lasing is demonstrated on the zero-dimensional states of single GaAs/GaAlAs
micropillar cavities. Under nonresonant excitation, the measured polariton ground-state …

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 …

We present a comprehensive analysis of critical behavior in the driven-dissipative Bose
condensation transition in three spatial dimensions. The starting point is a microscopic …

We show how to simulate a model of many molecules with both strong coupling to many
vibrational modes and collective coupling to a single photon mode. We do this by combining …
