Complex energies, quantum symmetries

In a certain sense, physics is the study of the universe's symmetries. Physicists strive to understand how systems and symmetries change under various transformations.

Physicists create world's smallest engine

Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine—which, as a single calcium ion, is approximately ten billion times smaller than a car ...

Researchers put a new spin on molecular oxygen

While pinning down a single oxygen atom sounds difficult, trying to then manipulate electrons associated with that single atom to alter its charge sounds downright impossible. However, for the first time, this achievement ...

The fun way to manipulate atoms

With their potential to perform calculations far beyond the reach of conventional supercomputers, machines harnessing certain quantum physics phenomena are expected to change the way the world solves complex problems. They ...

Macroscopic electron quantum coherence in a solid-state circuit

A team of researchers at the Centre de Nanosciences et de Nanotechnologies (C2N, CNRS/Univ. Paris-Saclay) has experimentally achieved the coherent propagation of electrons in circuits over macroscopic distances through a ...

Chemists manipulate the quantum states of gold nanoclusters

Researchers from Carnegie Mellon University's Department of Chemistry have found a way to control the lifetime of the quantum states of gold nanoclusters by three orders of magnitude, which could lead to improvements in solar ...
