(PhysOrg.com) -- For a couple of decades now, physicists have known that if a very small laser beam is pointed at a microscopic particle, it could be held in place due to the very small electrical field that is generated. ...
Physicists from Paderborn University have developed a novel concept for generating individual photons—tiny particles of light that make up electromagnetic radiation—with tailored properties, the controlled manipulation ...
