Superfluid helium has produced a narrow muonium beam, opening a path to test whether exotic particles fall like ordinary matter.

How can we predict the way a real material, such as a polymer, responds mechanically over timescales ranging from the ...

Griffith University researchers are conducting an experiment at ANSTO that will test a revolutionary physics theory that time reversal symmetry-breaking by neutrinos might cause a time dilation at the ...

Physicists at CERN have found a new way to peer deep inside atomic nuclei and distinguish between two competing explanations ...

The double-slit experiment is perhaps the most iconic demonstration in quantum mechanics: showing how a single particle’s ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.

A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with general relativity. Quantum mechanics is our best understanding of the ...

The intermediate range order of covalent glasses has been extensively studied in terms of the first sharp diffraction peak (FSDP), but the direct observation of the atomic density fluctuations that ...

Yuri Ralchenko led one of the oldest teams at the National Institute of Standards and Technology. The fate of some experiments hangs in the air. Lost Science Yuri Ralchenko led one of the oldest teams ...

To be useful, clocks need to be consistent. Imagine two spies who synchronize their watches; they rely on them agreeing days or months later, even if one of them must take a frigid hike through arctic ...
