For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...

Physicists in Israel have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...
