Physicists have been hoping for this moment for a long time: For many years, scientists all around the world have been searching for a very specific state of thorium atomic nuclei that promises ...

Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

At any given moment, trillions of particles called neutrinos are streaming through our bodies and every material in our surroundings, without noticeable effect. Smaller than electrons and lighter than ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

A team of physicists at UC Santa Barbara has seen the light, and it comes in many different colors. By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons ...

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced ...

Military researchers are now proving that drones do not always need to carry their own fuel or batteries. In recent tests, ...

researchers at Colorado University Boulder have used doughnut-shaped beams of light to take detailed images of objects too tiny to view with traditional microscopes. The researchers say that the new ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up ...
