(Phys.org) —Controlling the propagation of high-intensity light beams as they travel through air (or other transparent media) is a challenging task, but scientists have now shown that a relatively new type of light beam ...
(Phys.org)—A team of physicists in Israel has succeeded in generating an electron Airy beam for the first time. As they describe in their paper published in the journal Nature, the researchers used a technique similar to ...
We learned in science class that light beams travel in straight lines and spread through a process known as diffraction -- and they can't go around corners. But now researchers at Tel Aviv University are investigating new ...
