New quantum switch turns metals into insulators

Most modern electronic devices rely on tiny, finely-tuned electrical currents to process and store information. These currents dictate how fast our computers run, how regularly our pacemakers tick and how securely our money ...

Influential electrons? Physicists uncover a quantum relationship

A team of physicists has mapped how electron energies vary from region to region in a particular quantum state with unprecedented clarity. This understanding reveals an underlying mechanism by which electrons influence one ...

Research reveals new state of matter: a Cooper pair metal

For years, physicists have assumed that Cooper pairs, the electron duos that enable superconductors to conduct electricity without resistance, were two-trick ponies. The pairs either glide freely, creating a superconducting ...

New topological insulator reroutes photonic 'traffic' on the fly

Topological insulators are a game-changing class of materials; charged particles can flow freely on their edges and route themselves around defects, but can't pass through their interiors. This perfect surface conduction ...

Getting a look under the hood of topological insulators

Certain materials, like copper, conduct electricity very well. Other materials, like glass, do not. A certain kind of material, called a topological insulator, acts partially like one and partially like the other ― it ...
