A team of experimentalists at the U.S. Department of Energy’s Ames Laboratory and theoreticians at University of Alabama Birmingham discovered a remarkably long-lived new state of matter in an iron pnictide superconductor, which reveals a laser-induced formation of collective behaviors that compete with superconductivity.

“Superconductivity is a str...

Researchers for the first time apply catalytic chemical reactions to 2D sheets to generate flows that transform these sheets into mobile, 3D objects. The “magic carpet” featured in tales from “One Thousand and One Nights” to Disney’s “Aladdin” captures the imagination not only because it can fly, but because it can also wave, flap, and alter its shape to serve its riders...

Scientists at Tokyo Institute of Technology proposed new quasi-1D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. They performed simulations to demonstrate the spin properties of these materials and explained the mechanisms behind their behavior.

Conventional electronics is based on the movement of electrons and mainly concerns their electric charge; unfortunately, we are close to reaching the physical limits for improving electronic devices...

Engineers have succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering even when pathways turn sharply. These circuits may be suitable for use as high-frequency electromagnetic waveguides, which would allow miniaturization and high integration in various electronics devices, such as mobile phones.

There has been a surge in searching for materials with topological properties, whose functions are not influenced even if the sample shapes are changed...
