We study vacuum fluctuation properties of an ensemble of
gauge theory configurations, in the limit of many colors, viz.
, and explore the statistical nature of the topological susceptibility by analyzing its critical behavior at a non-zero-vacuum parameter
and temperature T
. We find that the system undergoes a vacuum phase transition at the chiral symmetry restoration temperature as well as at an absolute value of
. On the other hand, the long-range correlation length solely depends on
for the theories with critical exponent
is the decoherence temperature. Furthermore, it is worth noticing that the unit-critical exponent vacuum configuration corresponds to a non-interacting statistical basis pertaining to a constant mass of
