Summary 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.

Modern physics, and particularly the quantum theory — the discovery of Max Planck, the centennial of whose birth was celebrated last year —has raised a series of very general questions ...

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 ...

Bohr went on to make enormous contributions to physics and, like Rutherford, to train a new generation of physicists. But his atomic model remains the best known work of a very long career.

Scientists to present the latest in atomic, molecular and optical physics The 53rd Annual Meeting of the American Physical Society’s Division of Atomic, Molecular and Optical Physics begins May 30.

He reconciled the spectral lines and Rutherford’s nuclear atom with a new atomic model, in which electrons maintained stability of the atom but jumped from one orbit to another, emitting ...

The Geiger-Marsden experiment, also called the gold foil experiment, gave physicists their first view of the structure of the atomic nucleus.

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 a guitar string is plucked or a playground swing is set in motion, the movement gradually fades away. Physicists call these “damped harmonic oscillators,” and Newton’s laws do a fine job of ...

Researchers at CERN have made a great step forward in revealing how atomic nuclei behave after they mapped the edge of a ...
