A speed limit also applies in the quantum world

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. ...

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 ...

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 ...

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 ...

Hydrocarbon superconductor created

(PhysOrg.com) -- Scientists from Okayama University in Japan have discovered that the hydrocarbon picene can be made to superconduct when potassium atoms are interspersed with the picene crystals and the doped picene is cooled.

Most precise test yet of Einstein's gravitational redshift

(PhysOrg.com) -- While airplane and rocket experiments have proved that gravity makes clocks tick more slowly - a central prediction of Albert Einstein's general theory of relativity - a new experiment in an atom interferometer ...
