Louis E. Brus, a chemist and Nobel laureate who discovered quantum dots, tiny crystals that emit various colors of light ...

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

Liquids and solutions may look simple, but on the molecular scale they are constantly shifting and reorganizing. When sugar dissolves in water, each sugar molecule quickly becomes surrounded by fast ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...

For the first time, researchers have pushed electrons to flow so fast they went supersonic, creating a shockwave. The currents of electricity flowing through our devices share a name with river ...

Add Yahoo as a preferred source to see more of our stories on Google. Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage Team ...

Stephen L. Levy receives funding from the National Science Foundation and the National Institutes of Health. He is affiliated with CyteQuest, Inc. Richard Feynman, a famous theoretical physicist who ...

New method simulates electronic friction effects on quantum motion, explaining hydrogen diffusion on copper with relevance to catalysis and energy storage. (Nanowerk News) George Trenins and Mariana ...

Until now, atoms have never been imaged interacting freely in space, but a new technique known as non-resolved microscopy has changed that. MIT physicists were able to successfully capture images of ...
