A hybrid matter—an antimatter helium atom containing an antiproton, the proton's antimatter equivalent in place of an electron, has an unexpected response to laser light when immersed in superfluid ...

For the first time, an international team of scientists has succeeded in filming quantum physical effects on a helium dimer as it breaks apart. The film shows the superposition of matter waves from ...

It has been a long-time dream of the human race to be able to harvest resources from other places in the solar system, but we're only now getting to a point, technologically speaking, when we can ...

In Wednesday’s issue of Nature, a new paper describes a potentially useful way of measuring the interactions between normal matter and exotic particles, like antiprotons and unstable items like kaons ...

Helium atom precision measurements and calculations have a history of nearly a century. In the 1960s, theorists discovered that the fine-structure split (23P0-23P2) of the 23P energy level of helium ...

Physicists have developed the most sensitive method ever for measuring the potential energy of an atom (within a hundredth of a decillionth of a joule -- or 10-35 joule), and used it to validate one ...

How big is a helium atom? Or maybe the better question is: How small? After an intricate game of particle jockeying, physicists have now measured the radius of the helium nucleus five times more ...

Physicists, who dedicate their lives to studying the topic, don’t actually seem to like physics very much since they’re always hoping it’s broken. But we’ll have to forgive them; finding out that a ...

Physicists have created the first-ever atomic vortex beam — a swirling tornado of atoms and molecules with mysterious properties that have yet to be understood. By sending a straight beam of helium ...
