| contents | We present a non-perturbative holographic dual description for the \(O(N)\) vector model in \(d\)-dimensional Euclidean space within the functional renormalization group (FRG) framework. By continuously iterating Wilsonian RG transformations, the extra-dimensional scale coordinate is identified as the radial direction of an emergent \((d+1)\)-dimensional bulk spacetime. We construct a bidirectional holographic dictionary that maps non-perturbative fluctuations directly into the emergent bulk metric warping factors. Under the massless critical configuration, the emergent gravitational vacuum spontaneously organizes into a stable, regular Anti-de Sitter (\(\text{AdS}_{d+1}\)) geometry without coordinate singularities, satisfying all foundational local energy conditions. Near the thermal horizon, by systematically eliminating the conical deficit singularity, we rigorously prove that the semiclassical Hawking temperature identically matches the boundary field theory temperature (\(T_H \equiv T\)). Finally, we show that the near-horizon thermodynamic potentials exactly satisfy the First Law of Black Hole Thermodynamics, spontaneously generating the Bekenstein-Hawking area law (\(S_{\text{horizon}} = \frac{N}{4}\mathcal{A}\)) from a first-principles, bottom-up derivation. |
