When a group of Cornell physicists locked a particular gas in a vacuum chamber to cool, the atoms moved freely by “tunneling" to different positions. But, when researchers directly looked at the atoms, they realized that the tunneling would come to a stop. This observation effectively confirms E.C. George’s Quantum Zeno theory, which states that atoms won’t move while you’re looking at them. "This is the first observation of the Quantum Zeno effect by real space measurement of atomic motion," said Cornell's assistant professor of physics Mukund Vengalattore.
