A research team at the University of Delaware fabricated a tiny metalens - a thin lens that can be designed at the nanoscale to focus light in a specific way - on a silicon-based chip programmed with hundreds of tiny air slots, enabling parallel optical signal processing all within the tiny chip.
Researchers at the University of Innsbruck, funded by the US Army, achieved a record for the transfer of quantum entanglement between matter and light -- a distance of 50 kilometers was covered using fiber optic cables. Researchers said this brings the quantum internet a step closer. In a nonlinear crystal illuminated by a strong laser the photon wavelength was converted to the optimal value for long-distance travel.

The image depicts a schematic of terahertz (THz) heterodyne detection with graphene. In this, two THz waves (red) are coupled into graphene, where they are combined or mixed. One of the waves is a high intensity signal generated by a local THz light source (i.e. a local oscillator), at a known THz frequency. The other signal is a faint THz wave that mimics the waves coming from space.

Objects like Powehi, the recently imaged supermassive compact object at the center of galaxy M87, might actually be GEODEs. The Powehi GEODE, shown to scale, would be approximately 2/3 the radius of the dark region imaged by the Event Horizon Telescope.
Charge density waves are just the tip of the iceberg of the charge modulation phenomenon: charge density fluctuations are much more pervasive, and may be crucial to unlocking the secrets of high temperature superconductors.

Solar power will have drawn half - USD 1.3 trillion - of the USD 2.6 trillion in renewable energy investments made over the decade.
Combination of Faraday rotation and second-harmonic generation obtained the trajectory of an optically induced coherent spin precession. The time-resolved SHG is a valuable tool for the study of antiferromagnetic spin dynamics providing complementary information that is inaccessible by other techniques.
