Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

In the year 1900, no one would have guessed that light — to all appearances an ethereal wave-like phenomenon — might take the form of localized particles. Nor would anyone have expected that the ...

A new X-ray diffraction technique that works on single organic molecules has been demonstrated by an international team of researchers. The team hopes that, with further development, the method could ...

Do not exceed 10 mA of current! The electron diffraction tube is fragile. Handle with care. Turn down the high voltage when not in use. It is worthwhile to contrast the diffraction of electrons with ...

Although electron backscatter diffraction (EBSD) was first discovered by Kikuchi in 1928, its potential for microstructural characterization became fully realized only after the technique was ...

In 1967 the Russian physicist Victor Veselago predicted the existence of a material with a negative index of refraction, which he termed “left-handed.” He concluded that in the presence of such a ...
