近期，由中国科学院大学主导、多所学校参与的科研团队首次直接观测到米格达尔效应，这一发现为轻暗物质探测突破阈值瓶颈提供关键支撑。研究成果以“Direct observation of the Migdal effect induced by ...

The left side illustrates a schematic of electric field observation of the space charge layer at the grain boundary. An electron beam tilted at various angles (tilt-scan-averaged electron beam) scans ...

Schematic illustrations of (a) head-to-head (H-H) and (b) tail-to-tail (T-T) domain walls, respectively. These domain walls carry opposite polarization bound charges at their cores. In this study, a ...

Astronomers using the GRAVITY instrument at the VLT telescopes in Chile have now obtained the first direct confirmation of an exoplanet discovered by radial velocity. As the planet “Beta Pictoris c” ...
