Before showing the results on a SC antiferromagnet, let us emphasize the following point. The picture of de- fect clusters of down spins embedded in a up-spin sea that we used above
We report mathematical results, which define a func- tion µ under which quantum selection takes place: as the spin grows, low-energy quantum states localize on the set of phase space
