摘要: Abstract We study spectra, localization properties and local chirality of eigenvectors the lattice Dirac operator. analyze ensembles quenched SU(3) configurations on both sides QCD phase transition. Our operator is a systematic expansion in path length solution Ginsparg–Wilson equation. Analyzing finite volume behavior our observables their scaling with gauge coupling we come up consistent picture topological excitations results support interpretation dominant field seen by as fluid instanton-like objects.
