UNIVERSITY PARK, Pennsylvania, April 23 -- Pennsylvania State University issued the following news:
Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields. Despite this, researchers have now experimentally made light effectively "feel" a magnetic field within a complicated structure called a photonic crystal, which is made of silicon and glass. Within the crystal, the light spins in circles and the researchers observed, for the first . . .
