Abstract
We smear quenched lattice QCD ensembles with lattice volume by using Wilson flow. Six ensembles at temperature near the critical temperature corresponding to the critical inverse coupling are used to investigate the localization of topological charge density. If the effective smearing radius of Wilson flow is large enough, the density, size and peak of Harrington-Shepard (HS) caloron-like topological lumps of ensembles are stable when , but start to change significantly when . The inverse participation ratio (IPR) of topological charge density shows similar results, it begins to increase when and is stable when . The pseudoscalar glueball mass is extracted from the topological charge density correlator (TCDC) of ensembles at , and , the masses are 1.915(98) and 1.829(123) GeV respectively, they are consistent with results from conventional methods.
