Abstract

FINDING: Quantum tunneling is a wave-mechanical penetration of finite potential barriers, not a classical "jump"; its probability depends exponentially on barrier width and height, with no known teleportation mechanism. | MATH: Transmission coefficient $T \approx e^{-2\kappa L}$, where $\kappa = \sqrt{2m(V_0-E)}/\hbar$; for a rectangular barrier, exact $T = [1 + \frac{V_0^2 \sinh^2(\kappa L)}{4E(V_0-E)}]^{-1}$. No new constants or ratios emerge beyond $\hbar$, $m$, $V_0$, $E$, $L$. | CONNECTION: The exponential decay $e^{-2\kappa L}$ has no direct ratio to 0.382/0.618/1.618; however, the *critical* condition $E = V_0$ yields $\kappa = 0$ and $T \to 1$ (resonant transparency), which is a phase-transition-like threshold — analogous to a golden-ratio bifurcation point in some dynamical systems, but not evidenced here.
