Exploring quantum electron highways with laser light

Exploring quantum electron highways with laser light

The translucent crystal at the center of this illustration is a topological insulator, a quantum material where electrons (white dots) flow freely on its surface but not through its interior. By hitting a TI with powerful pulses of circularly polarized laser light (red spiral), SLAC and Stanford scientists generated harmonics that revealed what happens when … Read more

Researchers untangle the physics of high-temperature superconductors

Researchers untangle the physics of high-temperature superconductors

Credit: Unsplash/CC0 Public Domain When some materials are cooled to a certain temperature, they lose electrical resistance, becoming superconductors. In this state, an electric charge can course through the material indefinitely, making superconductors a valuable resource for transmitting high volumes of electricity and other applications. Superconductors ferry electricity between Long Island and Manhattan. They’re used … Read more

Scientists unravel ‘Hall effect’ mystery in search for next generation memory storage devices

Scientists unravel ‘Hall effect’ mystery in search for next generation memory storage devices

Credit: CC0 Public Domain An advance in the use of antiferromagnetic materials in memory storage devices has been made by an international team of physicists. Antiferromagnets are materials that have an internal magnetism caused by the spin of electrons, but almost no external magnetic field. They are of interest because of their potential for data … Read more

Newly discovered magnetic interactions could lead to novel ways to manipulate electron flow

Graphical representation of the crystal structure of the TbMn6Sn6 material at the atomic level. Here the Mn and Tb atoms appear as blue and green balls, respectively. Lines connecting near neighbors reveal the Mn Kagome and Tb triangular lattices. The magnetism present on this element is represented by arrows located on each individual atom. The … Read more
