The deconfinement transition in non-Abelian gauge theory is understood asspontaneous breaking of $\mathbb{Z}_N$ symmetry at high temperatures.Accordingly, quark-gluon plasma generally includes some partial cells calledcenter domains, each with a homogeneous Polyakov-loop expectation value. Inthis work, constructing an effective action describing the deconfinement vacuumof Yang-Mills theory with $N$ colors, we discuss the properties of centerdomains. First, we evaluate the spatial correlation of local Polyakov-loopfluctuation and demonstrate that some fluctuation becomes aNambu-Goldstone-like mode in the large-$N$ limit. We also discuss surfacetension between two $\mathbb{Z}_N$ center domains. Second, we estimate theglobal vacuum-to-vacuum transition in a single center domain. We find that somethreshold volume exists, where a domain larger than this volume is stable, andvice versa. Identifying the threshold as the lower bound of a stable centerdomain volume, we quantitatively argue the typical volume scale of centerdomains.
