Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold ...

MIT physicists have captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the "free-range" particles that until now were predicted but never ...

Two superfluids can exist at the same time in ultracold atomic clouds. Until now, their coexistence could not be observed experimentally. Now, however, physicists from Heidelberg University have ...

Using single-atom-resolved microscopy, ultracold quantum gases composed of two types of atoms reveal distinctly different spatial correlations — the bosons on the left exhibit bunching, while the ...

The images were taken using a technique developed by the team that first allows a cloud of atoms to move and interact freely. The researchers then turn on a lattice of light that briefly freezes the ...
