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.

"When an experiment turns out very different from what is expected, scientists start questioning previous assumptions and look for new explanations," says Kues. They jointly developed their new theory ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

In a paper published in Nature Photonics, the research team from the Center for Quantum Information and Communication – Ecole polytechnique de Bruxelles of Université libre de Bruxelles, has found an ...

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

Physicists in Leiden have recreated Thomas Young’s iconic double-slit experiment using gigahertz sound waves on gallium arsenide, revealing both parallels and differences with light. The study found ...

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

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 ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

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 ...
