Atomic and molecular physics is a discipline at the heart of understanding matter at its most fundamental level. Over the past century, pioneering experiments and theoretical breakthroughs have ...

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does ...

According to the researchers, Carnot determined the maximum efficiency of heat engines. He developed his principle, the ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...

In a study published in Nature Communications, a research team demonstrates the all-electrical control of quantum ...

MIT physicists improved the stability of optical atomic clocks by reducing “quantum noise” — a fundamental measurement ...

I'm completely stunned,' UC Berkeley professor says after winning a Nobel for work on quantum physics, the technology behind cell phones and more.

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

On Tuesday 7 October the winner(s) of the 2025 Nobel Prize for Physics will be announced. The process of choosing the winners is highly secretive, so looking for hints about who will be this year’s ...

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab. When you purchase ...
