This press release is available in German. Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus ...

Positronium shouldn’t last long enough to be interesting. It’s an “atom” assembled from an electron and its antimatter twin — a positron — locked in orbit around each other, destined to destroy ...

"Wave-particle duality is the cornerstone of quantum mechanics," says Xiaofeng Qian, the paper's lead author and an Assistant Professor of Physics at Stevens. "Researchers have been working to ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...
