Glimpses of the "gallium anomaly" were first seen in the mid-1990s, but it was first clearly discovered and stated in 2007 by neutrino physicist Carlo Giunti of Italy. The problem is simple to state but potentially very important: ...
Many complex quantum systems rapidly lose the recognizable patterns of their initial states as their components interact. To describe patterns of regular and chaotic motion in specific systems, physicists can construct a ...
For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an electron—into an exquisitely controlled quantum state.

Tiny atoms and molecules are constantly bombarding each other all around us. While we regularly measure the large-scale effects of these interactions, measuring the effect of each individual collision is far more difficult. ...
Whether we are waiting for a car windshield to defrost in winter or a warm drink to cool down, how long it takes for an object to settle into a stable, even temperature within its environment (thermal equilibrium) depends ...
Einstein's theory of general relativity describes gravity as the bending of spacetime, a mathematical model that combines three-dimensional space and time into a single, four-dimensional continuum. The theory also predicts ...
Some of the best engineers and inventors are copycats. They look at how the natural world solves complex problems and use those mechanisms as the basis for innovations. But Mother Nature doesn't always give up her secrets ...
Modern technological breakthroughs like lasers, MRI scanners, semiconductors and quantum computers rest on the study of quantum mechanics. However, the field has predominantly focused on (sub)atomic phenomena far removed ...

For decades, researchers around the world have been working toward this goal—and now major advances are following in rapid succession. Vienna is now home to the world's first nuclear clock that stabilizes itself, as atomic ...

Collisions between particles at high energies can sometimes produce new particles and shed light on interactions between the fundamental constituents of matter. Simulating these collisions and their underlying processes could ...
