Critical Electric Field in Charged Resonant Capacitors: A Prediction from the Stadler Lattice Model

We derive a quantitative prediction for the critical electric field Eᶜ observed by Minenkov and Bassan (arXiv:2509.21432) in charged resonant capacitors. Using the Stadler Lattice Model (V9), in which physical space is a cubic Planck lattice with invariant cell volume V_cell = lₘ³ = const., we obtain Eᶜ = 223.39 MV/m from three axioms and zero free parameters. The prediction agrees with the experimental mean of 223 MV/m to within 0.2%. The independence of Eᶜ from plate separation — confirmed experimentally — is a direct consequence of the model: the critical field is a property of the vacuum lattice, not of the mechanical system.
