The ability to describe the internal structure of atoms is important not only for understanding the composition of matter, but also for designing new experiments to explore fundamental physics.

Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still fully or partially filled with electrons. Studying the production mechanisms, ...

The positions of all the atoms in a sample of a metallic glass have been measured experimentally — fulfilling a decades-old dream for glass scientists, and raising the prospect of fresh insight into ...

An atom’s electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental ...

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM) have developed a novel method for investigating the internal structure of atoms and discovered ...

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

You've probably seen videos showing characters walking through walls like ghosts. Upon closer inspection, atoms consist of a vast majority of empty space. So why is physical reality so different?

High-order harmonic generation (HHG) provides a main route to generate attosecond (10-18 s) pulses, which have been considered “the world’s fastest film camera” for imaging the movement of electrons.
