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