Fermions do not travel together, theory proved
Fermions tend to avoid each other and cannot "travel" in close proximity. Demonstrated by a team at the Institut d'optique (CNRS/Université Paris 11, Orsay-Palaiseau), this result is described in detail in the January 25, 2007 issue of Nature. It marks a major advance in our understanding of phenomena at a quantum scale.   view more (2007-03-12)
