University of Adelaide researchers have delved into the realm of Star Wars and created a powerful tractor beam – or light-driven energy trap – for atoms. Rather than sucking space-ships into a space-station, this tractor beam pulls atoms into a microscopic hole at the center of a special optical fiber. It is opening the way for new quantum experiments that may lead to new secure communications or advanced sensing technologies. Published in the journal Physical Review Applied, the researchers fro...
