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 ...

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 ...

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, ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

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, ...

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 ...

For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be ...

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’ ...
