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...
Spooky apparition: ghost image made using atoms. (Courtesy: R I Khakimov et al./Nature) Ghost imaging – a counter-intuitive technique that produces images of an object using photons that have never interacted with it – has been performed for the first time using massive particles. The ...
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 ...

Assuming that an electron confined by double δ-function barriers lies in a quasi-stationary state, we derived eigenstates and eigenenergies of the electron. Such an electron has a complex eigenenergy, and the imaginary part naturally leads to the lifetime of the electron associated with tunneling...
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...
Naturally, reality moves on while the virtual stands still. Electrons move fast, but atoms faster still. As the ancients might have said, things change. ConsiderTerminal 115 viewpoint, already seen. Its gritty post-war beauty came not from the stagnant river or the military overpass, but from...
Thus, an important ingredient in the image analysis is to locate the centers of the atoms shown in micrographs as precisely as possible. Here, we consider scanning transmission electron microscopy (STEM), which acquires data in a rastering pattern, pixel by pixel. Due to this rastering ...
