Protons reveal universal phenomenon of maximal entanglement

When a high-energy photon strikes a proton, secondary particles diverge in a way that indicates that the inside of the proton is maximally entangled. An international team of physicists with the participation of the Institute ...

New dark matter theory explains two puzzles in astrophysics

Thought to make up 85% of matter in the universe, dark matter is nonluminous and its nature is not well understood. While normal matter absorbs, reflects, and emits light, dark matter cannot be seen directly, making it harder ...

Exotic atomic nucleus sheds light on the world of quarks

Experiments at CERN and the Accelerator Laboratory in Jyväskylä, Finland, have revealed that the radius of an exotic nucleus of aluminum, 26mAl, is much larger than previously thought. The result, described in a paper just ...

What a '2D' quantum superfluid feels like to the touch

Researchers from Lancaster University in the UK have discovered how superfluid helium 3He would feel if you could put your hand into it. Dr. Samuli Autti is the lead author of the research published in Nature Communications.

X-ray lasers: Why does brighter mean darker?

When we illuminate something, we usually expect that the brighter the source we use, the brighter the resulting image will be. This rule also works for ultra-short pulses of laser light—but only up to a certain intensity. ...
