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

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

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

Physicists confirm that light has two identities that are impossible to see at once. (Nanowerk News) MIT physicists have performed an idealized version of one of the most famous experiments in quantum ...

(Inside Science) — One of the strangest things about quantum mechanics is that a particle can act like a wave. In particular, in a double-slit experiment, individual particles that are shot through a ...

First experimental observation of matter-wave diffraction in a short-lived electronpositron atom using a graphene-based ...

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 ...
