Exploring quantum electron highways with laser light

Topological insulators, or TIs, have two faces: Electrons flow freely along their surface edges, like cars on a superhighway, but can't flow through the interior of the material at all. It takes a special set of conditions ...

Study finds nickelate superconductors are intrinsically magnetic

Electrons find each other repulsive. Nothing personal—it's just that their negative charges repel each other. So getting them to pair up and travel together, like they do in superconducting materials, requires a little ...

New leap in understanding nickel oxide superconductors

A new study shows that nickel oxide superconductors, which conduct electricity with no loss at higher temperatures than conventional superconductors do, contain a type of quantum matter called charge density waves, or CDWs, ...

How a soil microbe could rev up artificial photosynthesis

Plants rely on a process called carbon fixation—turning carbon dioxide from the air into carbon-rich biomolecules—for their very existence. That's the whole point of photosynthesis, and a cornerstone of the vast interlocking ...
