The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

Dark matter particles could be mediators of the interaction between electrons and atomic nuclei, as shown by a study ...

Cold atom experiments trap atoms to probe quantum effects, enabling ultra-precise sensing, timekeeping, and monitoring of Earth and space phenomena. (Nanowerk News) Cold atom experiments are among the ...

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 ...

Alloys created by mixing three atomic species (medium-entropy alloys, or MEAs) or five species or more (high-entropy alloys, or HEAs) have emerged as hot properties in materials science. In metallurgy ...

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 ...
