Topological photonics for single-photon sources
Light: Science & ApplicationsThe pursuit of high-quality single-photon sources has long been hampered by challenges in improving the performance and robustness. While traditional microcavity structures can achieve impressive performance, they suffer from extreme sensitivity to ...

Scientific ReportsWe introduce the gapped coherent state in the form of a single-photon source (SPS) that consists of uncorrelated photons as a background, except that we demand that no two photons can be closer in time than a time gap $$t_\text{G}$$ t G .

Melting and defect transitions in FeO up to pressures of Earth’s core-mantle boundary
Nature Communications, 2023 The high-pressure melting curve of FeO controls key aspects of Earth’s deep interior and the evolution of rocky planets more broadly. However, existing melting studies on wüstite were conducted across a limited pressure range and exhibit substantial ...

Single photon sources for absolute radiometry – A review about the current state of the art
Measurement: Sensors, 2021 In this presentation a review about the current state of the art concerning the application of deterministic single photon sources for absolute radiometry, i.e. the calibration of single photon detectors, is given.

Baryonic sources of thermal photons [PDF]
The European Physical Journal A, 2020 Thermal radiation of photons and dileptons from hadronic matter plays an essential role in understanding electromagnetic emission spectra in high-energy heavy-ion collisions. In particular, baryons and anti-baryons have been found to be strong catalysts for electromagnetic radiation, even at collider energies where the baryon chemical potential is ...

Sub-1.4eV bandgap inorganic perovskite solar cells with long-term stability
Nature Communications, 2020 Current research focus on the perovskites solar cells (PSCs) is mainly limited to the lead-based ones with bandgaps above 1.5 eV. Here Hu et al. report efficient and stable inorganic tin-containing PSCs, opening doors to exploring abundant perovskite ...
