A team of physicists has shown that pairs of helium atoms, chilled to near absolute zero and launched into each other, can ...

While probing single molecules or atoms typically requires liquid helium—a costly resource—to build a stable environment, a new development from a joint Chinese research team changes the game. By ...

For the engineer or scientist using spectroscopic laser diagnostics to investigate gas-phase media or plasmas, this book is an excellent resource for gaining a deeper understanding of the physics of ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths of a ...

A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and molecules, a fundamental process in physics that has implications for ...

AMO science does more than prime the pump from which our society’s material wealth flows. In addition to providing the basis for new technology, it also is a source of the intellectual capital on ...

Physicists are getting closer to controlling single-molecule chemical reactions -- could this shape the future of pharmaceutical research? Controlling matter at the atomic level has taken a major step ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...

Molecules: groups of atoms bonded together. Chemical Reaction: the process of atoms and molecules creating or breaking bonds; often leads to a change in color, smell, temperature, or other changes in ...
