Atomic and molecular physics addresses the structure and interactions of atoms and molecules, uniting quantum theory with experimental observation to explain phenomena from spectral lines to collision ...

Researchers at Humboldt-Universität zu Berlin have developed a new method for trapping and controlling atoms near an ...

Nuclear physics investigates the properties, structure and reactions of atomic nuclei, the dense assemblies of protons and neutrons bound by the strong nuclear force. Central themes include the ...

For decades, scientists have tried to build a device even more precise than an atomic clock, which keeps time using electrons, the negatively charged particles that whiz around in an atom. Now, two ...

Researchers have combined theory and experiments to show that nuclear polarization does not limit studies of muonic atoms, clearing the way for new nuclear physics experiments. University of ...

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 ...

University of Queensland researchers have made a breakthrough in muonic atom research, clearing the way for new nuclear physics experiments. A team at the UQ School of Mathematics and Physics has ...

For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new ...

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 ...

David Gross, a celebrated U.S. theoretical physicist, calls himself an optimist—especially concerning the future of his field. He’s certain that somewhere out there lurks a final, unified theory of ...
