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

Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

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

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

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

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

According to quantum mechanics, ordinary matter, not just light, can exhibit wave properties. The wave nature of matter is described by a 'quantum superposition' state, where physical states like posi ...
