Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among ...

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.

A new method turns noise into valuable data to enhance understanding of chemical reactions and material properties with unprecedented detail at the atomic level. The results of this research are now ...

Technical University of Braunschweig, and the University of Delaware achieved new insight into the inner structure of the ...

Researchers have used equipment originally intended for astronomy observation to capture transformations in the nuclear structure of atomic nuclei, reports a new study. A group of researchers have ...

Optical atomic clocks are the most accurate measuring instruments ever built and are becoming key tools for basic and applied research, for example to test the constancy of natural constants or for ...

Even if you’re one of the most precise physicists on the planet — as University of Delaware Professor Marianna Safronova is — you still will need collaborators whose skills complement your own and ...

For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

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 ...
