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.

For all our telescopes and colliders, dark matter has remained an elusive ghost for the better part of a century. It ...

Scientific clockmakers have crafted a prototype of a nuclear clock, hinting at future possibilities for using atomic nuclei to perform precise measurements of time and make new tests of fundamental ...

New study proposes using atomic clocks to probe the intersection of quantum mechanics and general relativity in spacetime.

Caltech scientists have developed an artificial intelligence (AI)–based method that dramatically speeds up calculations of ...

"Atomic clocks bring cosmology and astrophysics down to Earth, enabling searches for ultra-light particles that could explain dark matter in a laboratory." When you purchase through links on our site, ...

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 ...

Christopher Nolan's "Oppenheimer" tells the story of who created the first atomic bomb. The Manhattan Project required a fair amount of quantum physics and complex science. Here's a list of scientific ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The ...
