atoms exhibit non-local “Einstein–Podolsky–Rosen” (EPR) correlations between apparently localized properties such as momentum, so that a measurement of one can affect the state of the other. “Measuring EPR correlations with atoms has been a long-term goal of the field, and no one’s ...
Following structural dynamics in real time is a fundamental goal towards a better understanding of chemical reactions. Recording snapshots of individual molecules with ultrashort exposure times is a key ingredient towards this goal, as atoms move on femtosecond (10−15 s) timescales. For condensed...
Since individual Si and C atoms and even the SiC bilayer polarity could not be established from these HR images, the real twin law was deduced by taking into account that the coherent structural match at the interface could be guaranteed only by a 180 -rotation around [0001]. In order to...
Limitless energy.In February, physicists at the Joint European Torus (JET) near Oxford, UK, generated the highest sustained energy pulse ever created by fusing together atoms. Scientists hope that JET, a doughnut-shaped reactor, will help them to harness nuclear fusion, the process that powers ...

Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule. Key to the experiment, which appears in this week's issue of the journalNature, is the researchers' use of the energy of a molecule's own electron as a kind of "flash...
