Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

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

A destructive windstorm disrupted the power supply to more than a dozen atomic clocks that keep official time in the United States. Reading time 2 minutes The official standard time of the United ...

In physics, breakthroughs are rare. Experiments are slow, expensive and often end up refining, rather than rewriting, our understanding of the universe. But what if the only constraint on scientific ...

On August 6, 1945, the sky above the Japanese city of Hiroshima opened. A blinding flash, then a deafening sonic boom. An entire city pulverized in seconds. Thus began the nuclear age. Today, 80 years ...

Editor’s Note: This article contains potentially triggering material, including discussions of war, health effects of atomic bombs, child death and more. In August 1945, the United States dropped ...

The Department of Physics and Astronomy (DPA) has about 330 undergraduate (B.S.) and 310 graduate (Ph.D. and M.S.) alumni. In the U.S., doctoral alumni are employed as faculty, research scientists and ...

Most robots rely on complex control systems, AI-powered or otherwise, that govern their movement. These centralized electronic brains need time to react to changes in their environment and produce ...

In 1925, grad student Cecilia Payne first proposed that stars were mostly made of hydrogen and helium and shaped our understanding of the universe. This image, taken by the NASA/ESA Hubble Space ...

From nearly indestructible metals, like tungsten, to delicate clouds in the sky, atoms make up everything around us. But do these atoms ever touch each other? As with most topics in atomic physics, ...

Steven Lamoreaux, an atomic physicist whose research has contributed to our understanding of the dark matter that is bound to our galaxy, was recently appointed the Eugene Higgins Professor of Physics ...
