One of the most fundamental interactions in physics is that of electrons and light. In an experiment, scientists have now managed to observe what is known as the Kapitza-Dirac effect for the first ...

Electron beam oscillators utilising surface wave structures represent a key technology in the generation of high‐power electromagnetic radiation. By deploying relativistic electron beams in ...

In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of ...

Four years ago the first modern electron microscope was exhibited by the Siemens & Halske A.-G., in Berlin (TIME, June 6, 1938). Two years ago the R.C.A. Laboratories completed the first commercial ...

Electron holography is based on the fundamental principles of holography, which involves the recording and reconstruction of wavefronts. In holography, a hologram is created by capturing the ...

Researchers from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los ...

This is an electron wave quantum hologram displaying the initials "SU" of Stanford University. The yellow area is a copper surface. The holes in the copper are molecules of carbon monoxide. Constantly ...

Sung to the abbess’s lines in “Maria” from The Sound of Music: “How do you catch a wave like Maria? How do you grab a cloud and pin it down? Oh, how do you solve a particle like Maria? How do you hold ...

In a breakthrough discovery, scientists have unveiled a novel method for X-ray generation, offering enhanced flexibility in emitting X-rays in various directions or focusing them. A nurse checks the ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...

(Nanowerk News) One of the most fundamental interactions in physics is that of electrons and light. In an experiment at Goethe University Frankfurt, scientists have now managed to observe what is ...
