Abstract

According to recent studies on resurgence scenario of quantum systems, some\ntopological objects with fractional charges play an important role to see the\nresurgence structure. In this talk, we report a numerical evidence of the\nfractional-instantons of the SU(3) gauge theory. The fractional-instanton\nappears in a weak coupling regime, if the theory is regularized by an infrared\n(IR) cutoff via the 1-form twisted boundary conditions. The Polyakov loop is\nalso measured to investigate the center symmetry and confinement. The\nfractional-instanton corresponds to a solution linking two of degenerate\n\ℤ₃-broken vacua in the deconfinement phase. This talk is based on\nthe paper[1].\n
