Physicists in China have unveiled new clues to the origins of high-temperature superconductivity in an iron-based material just a single unit-cell thick. Led by Qi-Kun Xue and Lili Wang at Tsinghua ...

Atomic, molecular and optical (AMO) physics explores the quantum behaviour of electrons, atoms and light, and their mutual interactions across energy, length and time scales. In atoms and molecules, ...

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 ...
