IN some work here on the focusing of rotationally symmetrical electron beams in the energy-range 20–70 volts, we have come across cases of standing-wave patterns in the electron emission from the ...

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 ...

PROVIDENCE, R.I. [Brown University] — New research by physicists from Brown University puts the profound strangeness of quantum mechanics in a nutshell — or, more accurately, in a helium bubble.

Much has been made of the excessive power demands of AI, but solutions are sparse. This has led engineers to consider completely new paradigms in computing: optical, thermodynamic, reversible—the list ...

Time mirrors are very cool. They seem a bit magical, undoing the damage that time has done, at least under the right circumstances. For light and for water waves, we know how to make a mirror that ...

Visitors to Saint Paul’s in London are often astonished by the cathedral’s whispering gallery, where words spoken in a whisper along the curving wall of the dome can be heard anywhere along that same ...

It is found that the reconstruction of the electronic environment and the optimization of the electromagnetic attenuation mechanism are achieved by constructing a model of metal–support interaction ...

(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 ...
