abstract
We compute the topological susceptibility chi_t in SU(3) lattice gauge theory using fermionic methods based on the Atiyah-Singer index theorem. Near the phase transition we find a smooth crossover behavior for chi_t with values decreasing from (191(5) MeV)^4 to (100(5) MeV)^4 as we increase the temperature from 0.88 T_c to 1.31 T_c, showing that topological excitations exist far above T_c. Our study is the first large scale analysis of the topological susceptibility at high temperature based on the index theorem and the results agree well with field theoretical methods.

Density and correlations of topological objects near the transition temperature in lattice gluodynamics
At T/Tc=0.96 the measured dyon density is about 3 fm^-3, and equal-type dyons attract at short distance, in contrast to the repulsion assumed in the dyon-liquid model.
