This non-peer-reviewed exploratory preprint tests whether a coupled quantum Hamiltonian with one additional spatial coordinate can produce barrier transmission distinct from ordinary one-dimensional quantum mechanics when both calculations share exactly the same observable slice V(x,0). A prescribed self-similar Gaussian barrier is compared using three calculations: fixed-width 1D, shrinking identical-slice 1D, and full coupled (x,w) scattering with harmonic confinement. The shrinking 1D slice is itself non-monotonic, so an upward turn is not uniquely extra-dimensional. The full model nevertheless gives a quantitatively different curve, with a sampled minimum near V0=18 and T=9.87e-3 at V0=64 versus 6.09e-9 for the identical slice. This is a reproducible coupled-channel result within a mathematical toy Hamiltonian, not evidence that nature has an accessible fourth spatial dimension. The barrier family is prescribed rather than derived from a constitutive field law. The record includes the manuscript and a supplement containing code, complete numerical results, metadata, and convergence checks. ChatGPT and Sarvam AI assisted with brainstorming and language development. ChatGPT also assisted with literature triage, control design, numerical implementation and auditing, and drafting.

This exploratory preprint studies a controlled quantum-scattering toy model with an additional harmonically confined coordinate w. It compares a fixed-width one-dimensional barrier, the exact shrinking observable slice V(x,0), and the full coupled (x,w) Hamiltonian. The identical-slice control shows that the non-monotonic transmission turn is not unique to an additional coordinate, while the coupled calculation produces a quantitatively distinct transmission curve and a converged transverse-broadening signal. The action-coordinate hypothesis is S_E = f(w), with A = S_E / ħ. The original eleven-point parameter sweep gives a monotonic nonlinear locus when A is plotted against the center broadening Δw_rms. A new matched-state stress test independently changes longitudinal energy or transverse confinement and retunes the barrier to reproduce Δw_rms = 0.08, 0.18, and 0.35. The corresponding WKB actions spread by 50.2%, 31.1%, and 22.7% relative to the baseline; the exact-scattering exponent agrees, and a refined-grid calculation is stable. Thus a universal one-variable proxy A = F(Δw_rms) fails without refitting. This result does not falsify an otherwise unspecified microscopic relation S_E = f(w), because Δw_rms is an observable moment rather than the coordinate or tunneling path w. It shows that broadening alone is insufficient and that a richer state description or path-level definition is required. The work is non-peer-reviewed and does not claim evidence that nature has an accessible fourth spatial dimension. The supplement contains the calculation scripts, CSV data, numerical metadata, convergence checks, and figures; AI assistance is disclosed in the manuscript.
This educational technical note derives the leading semiclassical tunneling exponent for a one-dimensional particle in a static electrostatic potential from the local Dirac dispersion relation, and shows how the Schrödinger WKB result follows in the low-energy limit. It also introduces a hypothetical parameter lambda multiplying the quadratic relativistic term and compares the corresponding exponents for a defined rectangular barrier. The standard Dirac-WKB derivation reproduces established relativistic quantum mechanics; it is not presented as a new physical law. The lambda modification is exploratory and has no independent theoretical derivation or experimental support in this note. The numerical comparison is a sensitivity calculation for an illustrative 10 fm rectangular barrier with constant Delta = 0.1 MeV and mu*c^2 = 1118 MeV. It is not a realistic D-T interaction model or a prediction of a fusion reaction rate. The note does not claim cold fusion, anomalous fusion enhancement, or reactor-relevant performance. A one-particle Dirac equation does not describe the complete D-T nuclear collision, which involves composite nuclei, strong-interaction channels, spin, and plasma/environment effects. The cited 2026 D-D metallic-hydride study concerns ion-beam and electrochemical loading conditions and does not validate the hypothetical lambda model or establish self-sustaining fusion.

This speculative theoretical note develops a toy framework linking quantum tunneling (QT), quantum excitation (QE), local Jacobian/state-space evolution, and a proposed near-linear QT/QE mode. It derives epsilon_Q = A_Q k_Q, reviews the standard near-threshold tunneling limit kappa -> 0, and shows that coherent QT/QE dynamics can be continuous under Schrodinger evolution. The nonstandard FTL step is isolated as a separate requirement: a physically justified dispersion relation and an operational signaling test. No experimental evidence for faster-than-light signaling is claimed.

Abstract We validate Geometric Quantum Tunneling (GQT) within the MMA–DMF framework, where barrier transmission is not imposed as a postulate but arises as a rare, noise-assisted escape process generated by deterministic scalar-field dynamics coupled to a structured vacuum sector. The stochastic forcing is thermodynamically constrained by a strict fluctuation–dissipation closure and regulated by a finite ultraviolet (UV) cutoff at a fundamental scale 𝑀 ≃ 1.00 × 102 TeV. Using a one-dimensional rectangular barrier as a controlled benchmark, we report: (i) Schrödinger-like wavepacket dispersion at Nelson equilibrium; (ii) recovery of semiclassical WKB scaling through an exponential dependence of transmission on barrier width (linear ln 𝑇 vs. width with 𝑅2 > 0.99 and a consolidated WKB recovery error of 1.2%); (iii) quantitative agreement with transfer-matrix quantum mechanics across deep-tunneling, resonant, and classical-transport regimes (RMSE 0.042, 0.085, and 0.011, respectively); and (iv) a distinctive near-cutoff prediction in which transmission is strongly suppressed as 𝑉0/𝑀 → 1 (rapid suppression already near 𝑉0 ≈ 0.95𝑀, with an inferred cutoff near 0.98𝑀 in the consolidated summary). Control tests include ablations that disable the geometric coupling, for which tunneling vanishes as expected. Numerical stability and convergence are verified with a step-size constraint 𝑑𝑡 ≲ 0.01𝑀−1; validated runs use 𝑑𝑡 = 0.005𝑀−1 with a small measured energy-drift slope (3.4 × 10−6) over 𝑇max = 1000. Data, scripts, and numerical artifacts required to reproduce the reported benchmarks are provided in the accompanying replication package.
We present a technical validation of Geometric Quantum Tunneling (GQT) within the MMA-DMF framework. In this approach, barrier penetration is not postulated: it emerges as a deterministic, noise-assisted escape process generated by a scalar-field generalized Langevin dynamics whose stochastic sector is thermodynamically closed by a strict fluctuation--dissipation relation [1, 2] and regulated by a finite ultraviolet (UV) cutoff at a fundamental scale M≃1.00×102 TeVM \simeq 1.00 \times 10^{2}\,\mathrm{TeV}M≃1.00×102TeV. We report 1D benchmark results showing (i) Schrödinger-like dispersion calibration at Nelson equilibrium, (ii) WKB recovery via exponential transmission scaling with barrier width (linear lnT\ln TlnT vs width with R2>0.99R^{2} > 0.99R2>0.99 and a consolidated WKB recovery error of 1.2%), (iii) quantitative isomorphism against transfer-matrix quantum mechanics across energy regimes (deep-tunneling RMSE 0.042, resonant RMSE 0.085, classical-transport RMSE 0.011), and (iv) the distinctive “geometric wall” prediction that tunneling collapses as V0/M→1V_{0}/M \to 1V0/M→1 (rapid suppression already near V0≈0.95MV_{0} \approx 0.95MV0≈0.95M and an inferred cutoff near 0.98M0.98M0.98M in the consolidated summary). We include mandatory ablations via the geometric toggle αgeo\alpha_{\mathrm{geo}}αgeo (tunneling vanishes as αgeo→0\alpha_{\mathrm{geo}} \to 0αgeo→0), and stability/convergence constraints requiring Δt≲0.01 M−1\Delta t \lesssim 0.01\,M^{-1}Δt≲0.01M−1 with validated production operation at Δt=0.005 M−1\Delta t = 0.005\,M^{-1}Δt=0.005M−1 and an energy drift slope 3.4×10−63.4 \times 10^{-6}3.4×10−6 over tmax=1000t_{\max}=1000tmax=1000. Finally, we specify a reproducibility and integrity layer (bit-exact seed replay across hardware targets, deterministic checkpointing, and SHA-256 manifesting) intended to make the full pipeline externally auditable. The consolidated evidence supports that MMA-DMF reproduces standard low-energy tunneling phenomenology while making a falsifiable high-energy prediction tied to UV regulation.
This pedagogical technical note derives a connected model from a one-dimensional monoatomic lattice through acoustic phonons, strain, photoelastic refractive-index modulation, Stokes and anti-Stokes optical sidebands, and a conditional spin-population response. It explains why a realistic optical-to-spin step requires a platform-specific intermediate state or Raman pathway, and treats direct spin–phonon coupling as a separate route. Under a fixed-amplitude ideal two-level model, the note analytically derives spin responsivity to a phonon-frequency perturbation, checks a π-pulse numerical example, and identifies the first detuning-dependent term in the short-pulse expansion. The deposit includes the PDF, LaTeX source, numbered references and BibTeX bibliography, figures, and reproducibility scripts. This is a pedagogical synthesis and quantitative illustration; no new experiment or novelty claim is made.
