Correlation between neutron pairs observed in helium-8 nuclei

Atomic nuclei consist of nucleons such as protons and neutrons, which are bound together by nuclear force or strong interaction. This force allows protons and neutrons to form bound states; however, when only two neutrons ...

Using quantum technology to constrain new particles

Yet-to-be discovered axions and axion-like particles may be the key to explaining some of the deepest puzzles of our universe, such as dark matter and charge-parity violation in strong interactions. Several recent theories ...

Intense laser light modifies the pairing of electrons

The quantum-mechanical exchange interaction between electrons, a consequence of the Pauli exclusion principle, can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved ...

A versatile hydrogel network-repairing strategy

Hydrogen bond engineering can convey stretchability, toughness and self-healing properties to materials, although enhancement effects of conventional hydrogen bonds is limiting due to their weak interaction strength. For ...

The next step in understanding the interaction among hadrons

In a recently published article in Physical Review Letters, the ALICE collaboration has used a method called femtoscopy to study the residual interaction between two-quark and three-quark particles. Through this measurement, ...
