Physicists build an atom laser that can stay on forever

Lasers produce coherent waves of light: All the light inside a laser vibrates completely in sync. Meanwhile, quantum mechanics tells us that particles like atoms should also be thought of as waves. As a result, we can build ...

Designing the perfect piece of chocolate

We like some foods, and dislike others. Of course, the way food tastes is important, but mouthfeel, and even the sound that food makes when we bite it, also determine whether we enjoy the eating experience. Is it possible ...

Using ions to find molecules

When we think of ions, we usually think of single atoms that have lost or gained some electrons, but entire molecules can also become ions. In a new publication that was highlighted as an Editor's Suggestion in Physical Review ...

Study: Scientists carry greater credibility than spiritual gurus

What influence does the source of information have on its credibility? Scientists have more authority than spiritual sources, both among religious and non-religious people. This is apparent from a large-scale experiment conducted ...

Kinks, skinks and supersymmetry

Supersymmetry is symmetry of nature that is often hypothesized to exist among elementary particles. In a new paper that appeared in Physical Review Letters this week, physicists from the University of Amsterdam and QuSoft ...

A new method for quantum computing

Physicists from the University of Amsterdam have proposed a new architecture for a scalable quantum computer. Making use of the collective motion of the constituent particles, they were able to construct new building blocks ...
