Schematic of light-induced formation of Weyl points in a Dirac material of ZrTe5. Jigang Wang and collaborators report how coherently twisted lattice motion by laser pulses, i.e., a phononic switch, can control the crystal inversion symmetry and photogenerate giant low dissipation current with an exceptional ballistic transport protected by induced […]

Transmitter density means greater population exposure to high levels of radio frequency electromagnetic fields. We should err on the side of caution and stop the global roll out of 5G (fifth generation) telecoms networks until we are certain this technology is completely safe, urges an expert in an opinion piece […]

ANIMATION Researchers from the Moscow Institute of Physics and Technology (MIPT) have developed a prototype detector of solar particles. The device is capable of picking up protons at kinetic energies between 10 and 100 megaelectronvolts, and electrons at 1-10 MeV. This covers most of the high-energy particle flux coming from […]

Ultra-thin gold lamellae drastically amplify the incoming terahertz pulses (red) in the underlying graphene layer, enabling efficient frequency multiplication. Credit: HZDR/Werkstatt X On the electromagnetic spectrum, terahertz light is located between infrared radiation and microwaves. It holds enormous potential for tomorrow’s technologies: Among other things, it might succeed 5G by […]

An electrical current excites the superposition of two magnons with linear polarization (indicated by the red and blue arrows). Subsequently, energy is transported through the antiferromagnetic insulator. This can be detected as electrical voltage.

Switching points of the brain are simulated with magnetic waves, which are specifically generated and divided using nonlinear processes within microscopically small vortex discs. Credit: HZDR/Sahneweiß/H. Schultheiß Neural networks are some of the most important tools in artificial intelligence (AI): they mimic the operation of the human brain and can […]

Pictural representation of the molecule-based magnet and its magnetic properties. Credit: Rodolphe Clérac Magnets are to be found everywhere in our daily lives, whether in satellites, telephones or on fridge doors. However, they are made up of heavy inorganic materials whose component elements are, in some cases, of limited availability. […]
