TL;DR: X-ray photoelectron spectroscopy showed a maximum oxidation resistance for “magic-number” clusters containing 55 gold atoms, which suggests that gold-55 clusters may act as especially effective oxidation catalysts, such as for oxidizing carbon monoxide.

TL;DR: A Tamm-plasmon-polariton structure is implemented and the coupling to a monolayer of WSe2, hosting highly stable excitons is studied, featuring an anti-crossing between the exciton and photon modes with a Rabi-splitting of 23.5 meV.

TL;DR: The unique molecular structure of eGFP prevents exciton annihilation even at high excitation densities, thus facilitating polariton condensation under conventional nanosecond pumping, and is clearly evidenced by a distinct threshold, an interaction-induced blueshift of the condensate, long-range coherence, and the presence of a second threshold at higher excitation density that is associated with the onset of photon lasing.

TL;DR: In this article, the authors review the recent progress in the development of the key building blocks for gallium arsenide quantum photonics and the perspectives for their full integration in a fully functional and densely integrated quantum photonic circuit.

TL;DR: In this article, the uniaxial stress state of ZnO microwires grown by carbothermal reduction were studied with spatially resolved low-temperature photoluminescence.
