http://www.sciencedaily.com/releases/2010/07/100728131711.htm In an international first, physicists of the University of Innsbruck, Austria have experimentally observed a quantum phenomenon, where an arbitrarily weak perturbation causes atoms to build an organized structure from an initially unorganized one. The scientific team headed by Hanns-Christoph Nägerl has published a paper about quantum phase transitions in a one dimensional quantum lattice in the scientific journal Nature.
"Interaction effects are much more dramatic in low-dimensional systems than in three dimensional space," explains Hanns-Christoph Nägerl.
