Physicists observe diffusion of individual atoms in light bath

In a combination of experiments and theory the diffusion of individual atoms in periodic systems was understood for the first time. The interaction of individual atoms with light at ultralow temperatures close to the absolute ...

Quantum cycles power cold-atom pump

The idea of a pump is at least as old as the ancient Greek philosopher and scientist Archimedes. More than 2000 years ago, Archimedes allegedly invented a corkscrew pump that could lift water up an incline with the turn of ...

Solving hard quantum problems—everything is connected

Quantum objects cannot just be understood as the sum of their parts. This is what makes quantum calculations so complicated. Scientists at TU Wien have now calculated Bose-Einstein-condensates, revealing the secrets of the ...
