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) …

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 …

Polariton lasing is the coherent emission arising from a macroscopic polariton condensate
first proposed in 1996. Over the past two decades, polariton lasing has been demonstrated …

Under the right conditions, cavity polaritons form a macroscopic condensate in the ground
state. The fascinating nonlinear behaviour of this condensate is largely dictated by the …

Semiconductor microcavities offer unique systems in which to investigate the physics of
weakly interacting bosons. Their elementary excitations, polaritons—mixtures of excitons …

We observe the buildup of strong (<? format?>∼<? format?> 50%) spontaneous vector
polarization in emission from a GaN-based polariton laser excited by short optical pulses at …

We demonstrate experimentally the condensation of exciton polaritons through optical
trap**. The nonresonant pump profile is shaped into a ring and projected to a high quality …

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 …
