Physicists at MIT have developed a new microscope using terahertz light to directly observe hidden quantum vibrations inside a superconducting material for the first time. The device compresses terahertz light to overcome its wavelength limitations, revealing frictionless electron flows in BSCCO. This breakthrough could advance understanding of superconductivity and terahertz-based communications.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf have discovered previously unseen Floquet states inside extremely small magnetic vortices using minimal energy from magnetic waves. This finding, which challenges prior assumptions, could link electronics, spintronics, and quantum technologies. The results appear in Science.

Researchers have developed minuscule devices that use light to control movement in multiple directions, advancing the potential for light-powered spacecraft. The metajets, made from silicon, were tested in a lab setting and showed promising results for steering large sails through space. This breakthrough could help overcome current limitations in directing such vessels over vast distances.
Researchers using the DAMPE space telescope have identified a shared spectral softening in cosmic rays across multiple particle types. The pattern appears at a rigidity of about 15 teraelectron-volts for protons through iron nuclei. This finding, published in Nature, offers new insight into how these high-energy particles behave in the galaxy.
