Lattice QCD at finite temperature: Evidence for calorons from the eigenvectors of the Dirac operator
arXiv:hep-lat/0110182 · doi:10.1016/S0920-5632(01)01757-1
Abstract
We analyze the eigenvalues and eigenvectors of the staggered Dirac operator in quenched lattice QCD in the vicinity of the deconfinement phase transition using the Lüscher-Weisz gauge action. The spectral and localization properties of the low-lying eigenmodes show characteristic differences between the Z_3 sectors above the critical temperature T_c. These findings can be interpreted in terms of calorons.
