Researchers say they have observed parity-time symmetry breaking for the first time in an experiment. The result was obtained using a “dilation” technique on a single-spin system – a nitrogen-vacancy ...

So-called “higher symmetries” are illuminating everything from particle decays to the behavior of complex quantum systems. For that reason, research across physics is now building to a crescendo. It ...

Forget solid, liquid, and gas: there are in fact more than 500 phases of matter. In a major new article scientists reveal a modern reclassification of all of them. Forget solid, liquid, and gas: there ...

Initially regarded as a scientific curiosity upon its discovery in 1911 by Heike Kamerlingh Onnes, superconductivity has provided physicists with numerous theoretical challenges and experimental ...
