The concept of universal physics is intriguing, as it enables researchers to relate physical phenomena in a variety of systems, irrespective of their varying characteristics and complexities. Ultracold atomic systems are ...
(Phys.org) —Officially, the radius of a proton is 0.88 ± 0.01 femtometers (fm, or 10-15 m). Researchers attained that value using two methods: first, by measuring the proton's energy levels using hydrogen spectroscopy, ...
Our world is ruled by four fundamental forces: the gravitational pull of massive objects, the electromagnetic interaction between electric charges, the strong nuclear interaction holding atomic nuclei together and the weak ...

An international team of researchers has demonstrated a new way to gain a detailed understanding of what happens when two atoms meet. In their paper published in the journal Physical Review Letters, the group describes their ...
A group of theoretical physicists at Johannes Gutenberg University Mainz (JGU) has once again succeeded in significantly improving their calculations of the electric charge radius of the proton published in 2021. For the ...
