Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Researchers have shown that surprisingly large metal particles can behave according to quantum mechanics, existing in ...

Physicists have put thousands of atoms into a "Schrödinger's cat" state — smashing the record for the most macroscopic object to be observed in a quantum state. In a new study, researchers observed ...

Even for scientists who have dedicated their lives to understanding gravity, the force’s relentless downward pull is sometimes a drag. Consider, for instance, the researchers who study Bose-Einstein ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

As high school students see in experiments with water waves, and we observe and use with light waves in many optical devices, interference is a fundamental property associated with wave-like behavior.
