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.

Recent research reveals that quantum mechanics can supersede the second law of thermodynamics at the atomic scale, ...

Editor’s Note: Professor WERNER HEISENBERG, who was born in Duisburg in 1901, was awarded the Nobel Prize in Physics in 1932 for his work on the quantum theory. A member of the faculty of the ...

Physicists have made one of the highest performance atomic clocks ever. ­­ Their instrument, known as an optical lattice atomic clock, can measure differences in time to a precision equivalent to ...

Physicists at the University of Oxford have successfully linked two atomic clocks through quantum entanglement for the first time. The feat can help make these clocks so precise that they begin to ...

MIT researchers found that a hidden atomic order can persist in metals even after they undergo extreme processing. For ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, ...

The 53rd Annual Meeting of the American Physical Society’s Division of Atomic, Molecular and Optical Physics begins May 30. Scientists from around the world will present new findings on atoms, simple ...

Physicists at MIT have developed a new way to probe inside an atom's nucleus, using the atom's own electrons as "messengers" ...

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 ...

After the “Little Boy” and “Fat Man” nuclear bombs were dropped on Hiroshima and Nagasaki on August 6 and 9, 1945, Salvador Dalí became fascinated with atomic theory. In 1973, he reflected that the ...
