An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The results are an important stress test ...

Atomic, molecular and optical physics lies at the intersection of quantum mechanics and electromagnetic theory, providing the fundamental framework for our understanding of matter and light.

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up of my favourite research of 2025 I have chosen five stories in which ...

Photoionization, the process by which an incident photon ejects an electron from an atom, lies at the heart of many atomic physics studies. Coupled with cross section measurements – which quantify the ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Professor Daniel Blumenthal's lab develops chip-scale components that can bring the power and precision of quantum science outside of the tightly controlled environment of the lab. (Santa Barbara, ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

In March 2018, researchers launched what looks like a white, cooler-sized fridge to the International Space Station. That heavy box houses a $100 million facility known as the Cold Atom Laboratory, ...

If an atomic physicist like Nathan Lundblad could slip the surly bonds of Earth’s gravitational pull, what kind of experiment would he dream up? About a decade ago, that very question was posed to ...

While many Earth-based experiments have been run to try to detect dark matter, the mysterious substance remains elusive. Now physicists have proposed a new experiment that would try to find signals by ...

A team has succeeded in computing how atomic nuclei of the Calcium element behave in collisions with electrons. Results agree very well with available experimental data. For the first time, a ...

Nuclear clocks could be the GOAT: Greatest of all timepieces. If physicists can build them, nuclear clocks would be a brand-new type of clock, one that would keep time based on the physics of atoms’ ...
