Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold ...

When atoms collide, their exact structure—for example, the number of electrons they have or even the quantum spin of their ...

From nearly indestructible metals, like tungsten, to delicate clouds in the sky, atoms make up everything around us. But do these atoms ever touch each other? As with most topics in atomic physics, ...

The nucleus of the Xenon atom can assume different shapes depending on the balance of internal forces at play. As two Xenon atoms collide in the CERN experiment, extremely hot conditions are created ...
