TUR saturation at minimal dissipation: Var(J) = 2k_B<J>^2/<Sigma>; ratio = 2*k_B/<Sigma>

Layer 1 — Physicsin the quantum-thermodynamics subtree

TUR saturation regime: fractional-uncertainty floor. From framework F9 (TUR), the equality Var(J)/<J>^2 = 2*k_B/<Sigma> is saturated by near-equilibrium Gaussian fluctuations where the rate-function I(j) ~ (j - <J>)^2 / (2*Var(J)) is…
