Physicists split an atom using quantum mechanics precision

Researchers from the University of Bonn have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum ...

A quantum simulation of Unruh radiation

Researchers at the University of Chicago (UChicago) have recently reported an experimental observation of a matter field with thermal fluctuations that is in accordance with Unruh's radiation predictions. Their paper, published ...

Physicists stop and store light traveling in an optical fiber

Researchers at the Kastler Brossel Laboratory in Paris have managed to store light that propagates in an optical fiber and to release it later on demand. By causing interaction between the traveling light and a few thousand ...

Scientists discover magnetic superatoms

A team of Virginia Commonwealth University scientists has discovered a 'magnetic superatom' - a stable cluster of atoms that can mimic different elements of the periodic table - that one day may be used to create molecular ...

A rock is a clock: Physicists use matter to measure time

What is the simplest, most fundamental clock? Physicist Holger Müller and his UC Berkeley colleagues have shown that a single atom is sufficient to measure time using its high-frequency matter wave. Conversely, the frequency ...
