TL;DR: In this article, topologically protected lasing is reported in a one-dimensional lattice of polariton micropillars that implements an orbital version of the Su-Schrieffer-Heeger Hamiltonian, which offers new opportunities for robust trapping of light in nano-and micrometre-scale systems subject to fabrication imperfections and environmentally induced deformations.

TL;DR: In this paper, topological edge states of a one-dimensional lattice of polariton micropillars that implements an orbital version of the Su-Schrieffer-Heeger Hamiltonian were shown to persist under local deformations of the lattice.

TL;DR: Experimental studies of honeycomb lattices where the polariton low-energy dispersion is analogous to that of electrons in graphene, using energy-resolved photoluminescence to directly observe Dirac cones, around which the dynamics of polaritons is described by the Dirac equation for massless particles.

TL;DR: This work reports on the fabrication of ultrabright sources of indistinguishable single photons, thanks to deterministic positioning of single quantum dots in well-designed pillar cavities, and shows that a two-laser excitation scheme allows reducing the fluctuations of the quantum dot electrostatic environment under high pumping conditions.

TL;DR: The engineering of a nondispersive (flat) energy band in a geometrically frustrated lattice of micropillar optical cavities offers a novel approach to studying coherent phases of light and matter under the controlled interplay of frustration, interactions, and dissipation.
