TL;DR: It is demonstrated that non-Hermiticity dramatically modifies the structure of modes and spectral degeneracies in exciton-polariton systems, and, therefore, will affect their quantum transport, localization and dynamical properties.

TL;DR: In this paper, an exciton-polariton topological insulator was shown to be possible without a magnetic field in an array of semiconductor microcavities, where an applied magnetic field leads to the unidirectional flow of a polariton wavepacket around the edge of the array.

TL;DR: The experimental realization of room-temperature polariton lasing based on an epitaxy-free all-inorganic cesium lead chloride perovskite nanoplatelet microcavity is reported, suggesting considerable promise of lead halideperovskites toward large-area, low-cost, high-performance room- temperature polariton devices and coherent light sources extending from the ultraviolet to near-infrared range.

TL;DR: Couple quantum modes can be strongly sensitive at the single quantum level, even if nonlinear interactions are modest, and solid-state implementations based on the tunneling of polaritons between quantum boxes or their parametric modes in a microcavity are considered.

TL;DR: In this article, the optical spin Hall effect was observed in a high-quality GaAs/AlGaAs quantum microcavity, where the spin current was controlled by the linear polarization of the laser pump.
