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: 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.

TL;DR: It is proved that the predictive mean and the variance of the presented approach are identical to the ones of the original co-kriging model, and the proposed approach has a reduced computational complexity compared to the previous one.

TL;DR: In this article, a multi-fidelity co-kriging model based on a recursive formulation is proposed to build a surrogate model of a complex computer code which can be run at different levels of accuracy.
