Explainer: What is a superconductor?

Materials can be divided into two categories based on their ability to conduct electricity. Metals, such as copper and silver, allow electrons to move freely and carry with them electrical charge. Insulators, such as rubber ...

Researchers discover fastest light-driven process

(Phys.org)—A discovery that promises transistors – the fundamental part of all modern electronics – controlled by laser pulses that will be 10,000 faster than today's fastest transistors has been made by a Georgia State ...

Strange things happen when a crystal is split in two

The remarkable strength of ionic crystals is easily explained at the atomic scale: Positively and negatively charged atoms sit side by side in a repeating periodic arrangement. The strong electrostatic force in between keeps ...

Broadband invisibility in the microwave range

(PhysOrg.com) -- In the series Star Trek, Klingons and Romulans have spaceships outfitted with cloaking devices that hide their presence from sight, as well as from the sensors of their rivals' spaceships. Unlike current ...

Diamonds show promise for spintronic devices

Conventional electronics rely on controlling electric charge. Recently, researchers have been exploring the potential for a new technology, called spintronics, that relies on detecting and controlling a particle's spin. This ...

Scientists discover giant Rydberg atom molecules

A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red blood cell. Determining ...
