A 2×2 multiplexed GaAsSb nanowire photodetector array integrated with L‐shaped metasurfaces is developed for miniaturized infrared polarimetry. Leveraging non‐radiating anapole states that facilitate near‐field enhancement, the device demonstrates strong polarization selectivity at 835 nm.

Regards sur la nature : place de l’observation dans les textes astronomiques latins
In antiquity, astronomical knowledge came essentially from philosophy, mathematics and logic. One can then question the role given to the observation of phenomena. To answer this question, we chose to analyze some of the demonstrations presented in Latin

The 1948 solar eclipse and the genesis of radio astronomy in Victoria [PDF]
In the early years of radio astronomy, solar eclipses played a critical role in establishing the sources of solar radio emission. During the half decade from 1945, Australia emerged as a leading nation in radio astronomy, with most of the observations ...

The symmetry‐driven coexistence of altermagnetism and (anti)ferroelectricity in perovskites shows a strong dimensional dependence. Upon reducing the system from bulk to the two‐dimensional limit, only C‐type antiferromagnetic order retains ferroelectrically switchable altermagnetism, whereas A‐ and G‐type orders become conventional antiferromagnets ...
