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 proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets ...

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 ...

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 ...

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change ...

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.
