Physicists are no longer content to let atoms blur into invisibility. By squeezing light into pulses that last just ...

The 20th century was marked by the discovery of exotic states of matter. First, liquid helium was observed to flow without friction at extremely low temperatures, a phase now known as superfluid. Soon ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By ...

Physicists at the MIT-Harvard Center for Ultracold Atoms have pulled off a feat once confined to the blackboards of theorists: they’ve taken the first direct images of atoms freely interacting in ...

The manipulation of neutral atoms by light is one of the most important scientific discoveries in the field of quantum physics in the last three decades. Researchers show that increasing the number of ...

The energy state of an atom is denoted by its principal quantum number, designated n, which defines the probability of ...

Entangled atoms, separated in space, are giving scientists a powerful new way to measure the world with stunning precision.

Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold gas of atoms confined to a single line, countless collisions occur—but ...

Atoms are normally made of a nucleus and electrons. But scientists are proposing a hunt for a new variety of atom without either. Tauonium (sometimes called “ditauonium” or “true tauonium”) would ...
