Discrete Graph-Cuts and Evanescent Quantum Walks: A Bipartite Derivation of Alpha Decay and Gamow Tunnelling

Abstract

WITHDRAWAL NOTICE (18 October 2026). This paper is withdrawn and should no longer be cited as a result. It is built on a lattice geometry — the truncated cubic honeycomb ("Z3 ⊗ Q3"), with octagonal faces and regular-octahedron cells — that the framework retired between June and September 2026. The theorems and mechanisms tied to that geometry were withdrawn [G81, G84]. Its mechanism needs one nucleon per lattice cell, a packing withdrawn with the ħc/Λ lattice step [G100]; what remains is the standard Gamow tunnelling calculation. The research programme was concluded in October 2026; its review found the framework's Standard-Model content assigned rather than derived. The original description is kept below for the record. Original description (kept for the record): We reformulate alpha decay as a two-stage algorithmic process on a discrete Z3 ⊗ Q3 topological lattice. Standard continuous wave mechanics models the propagation of an alpha particle through a Coulomb barrier (Gamow tunnelling) but relies on phenomenological fits for the preformation prob- ability and assault frequency (the Geiger-Nuttall intercept). In this framework, the pre-tunnelling rate is derived as a calculable geometric edge-cut problem. Feshbach projection of the lattice walk operator yields a detachment rate of 1/36 per severed macroscopic gauge bridge. Assuming rapid many-body decoherence renders this a Markov process, the detachment rate scales as 36−k , where k is the integer number of boundary bridges. For a 2 × 2 cluster detaching via a minimal topological neck (k = 2), the framework predicts a pre-tunnelling emission rate of 1.14 × 1020 s−1, recovering empirical preformation phenomenology without fitted parameters. Post-detachment, the evanescent spatial propagation takes the form of a discrete tight-binding Riemann sum, which converges to the standard macroscopic WKB phase integral, explicitly recovering the 2πα√2mαc2 Gamow slope. Evaluating this unified equation end-to-end for 238U and 212Po yields effective barrier radii perfectly consistent with standard diffuse nuclear surfaces.

Eight Easy Pieces: The Information Lattice

David Elliman

WITHDRAWAL NOTICE (18 October 2026). This paper is withdrawn and should no longer be cited as a result. It is built on a lattice geometry — the 4.8.8 tiling ("circlette") and the truncated cubic honeycomb, with octagonal faces and regular-octahedron cells — that the framework retired between June and September 2026. The theorems and mechanisms tied to that geometry were withdrawn [G81, G84]. Its headline results — among them the fine-structure constant and the Planck mass — have since been withdrawn [K13, G99]; later accounts are 10.5281/zenodo.20962395 and 10.5281/zenodo.22650175. The research programme was concluded in October 2026; its review found the framework's Standard-Model content assigned rather than derived. The original description is kept below for the record. Original description (kept for the record): What if empty space is not empty — and not continuous? What if the vacuum is a crystal, built from quantum error-correcting codes, whose geometry produces the particles and forces of nature as naturally as ice produces snowflakes? This nine-part series traces a path from the measured reality of the quantum vacuum — the Casimir effect, the Lamb shift, the 10¹²¹ catastrophe — through the Standard Model's extraordinary successes and stubborn failures, to a specific, concrete proposal: an 8-qubit code on the faces of octahedral voids, self-organised into a three-dimensional honeycomb lattice, reproducing the 45 known fermions of the Standard Model from three Boolean rules and a single quantum logic gate. The series derives fundamental constants (including the fine-structure constant to 3 parts per billion) from counting faces and bridges, demonstrates spontaneous crystallisation of the lattice from unstructured qubit soups via simulated annealing, and dissolves the famous paradoxes of quantum mechanics — entanglement, wave function collapse, the double slit, Bell's theorem — into mechanical consequences of qubits propagating through a discrete geometry. Each article is self-contained and accessible to any numerate reader. Full mathematical derivations are linked as companion documents. Fourteen falsifiable predictions are stated explicitly, and every open problem is honestly catalogued. The framework may be wrong — but it is precise enough to be shown wrong, and that is what separates physics from philosophy. The title nods to Richard Feynman's "Six Easy Pieces." Feynman needed six. The octahedron needed eight. The paradoxes needed one more.

Spontaneous Crystallisation of Q3 Octahedra from Unstructured Qubit Networks under Simulated Quantum Annealing

David Graham Elliman

WITHDRAWAL NOTICE (18 October 2026). This paper is withdrawn and should no longer be cited as a result. Its central result cannot be reproduced: as its own June note records, the original code was lost and four reimplementations reached 0–17% against the reported 94%; without the lattice embedding another graph beats the claimed structure at the paper's own weights [G3], and the truncated-cubic assembly it targets has been retired [G84]. The research programme was concluded in October 2026; its review found the framework's Standard-Model content assigned rather than derived. The original description is kept below for the record. Original description (kept for the record): We demonstrate via simulated annealing that an unstructured network of N qubits, subject only to a degree-3 regularity constraint and spectral energy minimisation, sponta- neously partitions into ⌊N/8⌋copies of the Q3 hypercube graph — the unique 3-regular, vertex-transitive graph on 8 vertices supporting a distance-4 error-correcting code realis- able as the face-adjacency graph of a regular octahedron in three dimensions. Over 100 independent trials from random initial conditions with N = 24, perfect Q3 crystallisation occurs in 94% of runs. We prove that Q3 is the unique optimal target by ruling out all competing graphs on independent geometric and coding-theoretic grounds: the Petersen graph fails both the convex polyhedral embedding test and the 4-cycle (distance-4 parity check) requirement. Frustrated configurations (N ̸≡0 (mod 8)) produce high-energy partial clusters that cannot close their parity-check circuits, providing a discrete model of quantum vacuum fluctuations. When inter-cluster bonding is permitted, the isolated octahedra spon- taneously form bridge connections, assembling into a connected lattice network. The code and all simulation data are publicly available for independent reproduction.

Emergent Minimal Gauge Coupling from C4v Symmetry Reduction on the 4.8.8 Lattice

David Elliman

WITHDRAWAL NOTICE (18 October 2026). This paper is withdrawn and should no longer be cited as a result. It is built on a lattice geometry — the 4.8.8 tiling ("circlette") — that the framework retired between June and September 2026. The theorems and mechanisms tied to that geometry were withdrawn [G81, G84]. Its matrix element is a band velocity, not a gauge coupling, and fixes no interaction [K8, G84]; the velocity unification it supports was withdrawn [K7]. The research programme was concluded in October 2026; its review found the framework's Standard-Model content assigned rather than derived. The original description is kept below for the record. Original description (kept for the record): We analyse the symmetry structure of the continuous-time quantum walk on the 4.8.8 (truncated square) Archimedean tiling, whose bifurcated band structure was recently char- acterised via OTOC echo protocols [1]. Decomposing the 8 ×8 Bloch Hamiltonian into irreducible representations of the C4v point group at the Γ point, we show that the gapped slow branch transforms as the fully symmetric scalar representation A1, while the gapless fast branches transform as the two-dimensional vector representation E. At Γ, the Wigner-Eckart theorem enforces strict orthogonality between these sectors: ⟨A1|H|E⟩= 0. Away from Γ, symmetry reduction C4v →Cs breaks this selection rule. We compute the inter-branch matrix element exactly and find M=− i 2 sin kx for the Ex component, yielding a momentum- linear vertex M∝i(k·E) that is structurally identical to the p·A minimal coupling of quantum electrodynamics. We then promote the tight-binding hopping amplitudes to dy- namical U(1) link variables in a Wilson lattice gauge theory, demonstrate via a weak-field expansion that the gauge-covariant Hamiltonian reproduces the same vertex, and identify a two-coupling structure (β4,β8) rigorously locked by the tiling geometry. We formulate the velocity-unification conjecture—that renormalisation group flow drives the distinct bare group velocities toward a common infrared fixed point—as a concrete numerical programme for lattice Monte Carlo simulation.

Foundations and Methodology for a Finite-QEC Substrate: Code, Crystallisation, Ledgers, and Audit Protocol

David Elliman

STATUS (18 October 2026). The research programme this paper belongs to — the finite-QEC substrate ("It from Bit") framework — was concluded in October 2026. The author's review found that the framework's Standard-Model content is assigned rather than derived and that no verified prediction yet distinguishes it from standard physics. The claim of a unified derivation is withdrawn. This paper's results are unaffected except where noted below. Current gravity work: 10.5281/zenodo.23458252. ERRATUM — fine-structure constant (18 October 2026). This paper quotes the framework's value of the fine-structure constant, α−1(0) = 137.035999106904 (or the earlier 137.035999077), as agreeing with experiment. That statement is withdrawn. (1) On 11 August 2026 the value was corrected to 137.0359991069051: the earlier figure came from an extrapolation fitted at the wrong order. Against current determinations the corrected value sits −2.26σ from the caesium-recoil value, +9.01σ from the rubidium-recoil value and +3.94σ from the electron-g−2 route. Those determinations disagree with one another, so no single agreement figure can be quoted [K13]. (2) The second-order coefficient behind the value was computed on a four-dimensional hypercubic lattice that the framework's own geometry does not supply. Recomputed on that geometry under a pre-registered procedure, the same formula gives 137.0359985927, 4.26 parts per billion below CODATA 2022, so the claimed agreement does not survive [G87, G88, 24 September 2026]. The bare count α0 = 1/137 used in the paper is a premise of the framework, not a derived result. Noted: the methodology, the byte construction (with its CSS step stated as a hypothesis, consistent with [R22]) and the 28-step clock stand. Its fine-structure value is corrected by the erratum above; its "bi-cubic" picture of the cell differs from the framework's locked bond-bipyramid cell [G84]; and full strain readout does not preserve all logical coherence [G90]. States the foundational objects and audit methodology of the finite-QEC (quantum-error-correction) substrate program: the eight-bit local code, the bi-cubic crystallisation picture, the distinction between syndrome and strain readouts, the 28 = 2×14 service-clock construction, and the methodological rules that classify every claim as locked, computed, conditional, retired, or open. The goal is to make the companion physics papers auditable: every coefficient must name its carrier, event unit, scheduler, observable map, and reproducibility check. Version 3.0. Added a radiation-sector domain-of-validity caveat (the emergent gauge sector is an effective theory below the substrate's Brillouin scale; trans-cutoff single photons are an open foundational question) and the relativity companion citation.

Gamow Factor Derivation Applied to n1-n2 (index of refraction) Reflection-Refraction

Francesco R. Ruggeri

In (1), an outline of the derivation of the Gamow factor for alpha decay from a nucleus is given. In one dimension, the approach considers three regions in space, one with an incident and reflected free particle wavefunction, the second (within a square V barrier) with an exponentially growing and falling solution, and the third, with a single free particle wavefunction exp(-iEt)exp(ipx+phase) representing the escaped alpha particle. Alpha decay is treated as a quantum tunneling problem and the wavefunction and its first derivative d/dx must be continuous. A second step in (1), however, is to assume that one may write a time related wavefunction as exp(- g t), where d/dt partial Integral dx (region) W*W = ½ (-i W* d/dx W + i W d/dx W*). This may appear to be a quantum mechanical equation, but we argue that this is nothing more than the classical continuity equation. In fact, in (2) we argued that quantum mechanics does not exist without classical equations. In particular, the quantum free particle wavefunctions exp(-iEt) and exp(ipx) follow exp(iEt)exp(-iEt) = 1 and exp(-ipx)exp(ipx) = 1 to link them classical densities in time and space for particles moving with a constant speed. If there is a decay in time and space, then the appropriate classical equation is the continuity one. Writing d/dt partial d(t) = constant d(t) yields the familiar exp(-g t) form. We apply the ideas of the Gamow factor to a set of photons bouncing back and forth in an n1 1-dimensional cavity surrounded by n2 (n2>n1) index of refraction material. In this case, if the photons are synchronized then one may follow them classically. The catch is that the probability to reflect or refract is quantum. In general, one would not write exp(-g t) in such a scenario, but would formally write an equation of the form: fraction of remaining photons = R power Integer(t/t1), where R is the probability to reflect and integer(t/t1) is the number of cycles.. If, however, the probability to refract is very small, we show that one may in fact obtain the same result as in the case of exp(- g t) for g <<1. Alternatively, if the cavity is small in length and the speed of the particle (c in the case of light) is large, one could approximate the situation by d/dt partial d(t)= constant d(t) and then obtain exp(-g t), having the photons no longer in deterministic motion.

From Scattering to Tunneling: Three-Dimensional Quantum Barrier Penetration and Its Application to α-Decay

Chongjing Li

This study investigates three-dimensional quantum tunneling through analytical solutions of the Schr¨odinger equation in Cartesian and spherical coordinates. By develop ing transmission coefficients for both square and spherical potential barriers, we establish a theoretical framework for α-decay via the Gamow model. The analysis reveals how angular momentum and energy dependence govern tunneling probabilities, with experimental valida tion showing agreement within 15% for high-energy decays. The results bridge fundamental quantum mechanics with nuclear physics applications.
