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 TlocT_{\mathrm{loc}} in the range 155MeVTloc158MeV155\,\mathrm{MeV}\le T_{\mathrm{loc}}\le 158\,\mathrm{MeV}, in excellent agreement with the pseudocritical crossover temperature as determined from the chiral condensate and from the light-quark susceptibility.
