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 ...

Helium—the lightest atom that can be laser-cooled and controlled—powers a new design for high-powered, stable quantum computers. In a paper published in PRX Quantum, a team led by University of ...

An elusive type of atom known as pionic helium has been directly excited by laser light for the first time. The work establishes a promising experimental platform for probing fundamental physics. Read ...

Lace, a startup backed by Microsoft, has raised $40 million to build chipmaking equipment based on helium atom beam lithography, a technique that could etch circuit designs 10 times smaller than ...

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 ...

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 ...

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 ...

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 ...

Helium is an element with many remarkable properties. The helium atom is smaller than that of any other element, and helium is second only to hydrogen in lightness. It has a particularly stable and ...

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 ...
