Abstract
We study the localization properties of the low-lying Dirac eigenmodes in QCD near the crossover temperature, using staggered fermions on the lattice. We find that localized low modes, absent at low temperature, appear at a temperature in the range , in excellent agreement with the pseudocritical crossover temperature as determined from the chiral condensate and from the light-quark susceptibility.
