The Mott Problem Revisited: Collapse Geometry, Resonant Measurement, and Trajectory Formation

Young, Charles

Published Dec 16, 2025• 0 citations
Publisher

Abstract

The Mott problem concerns a long-standing paradox in quantum mechanics: although alpha-particle wavefunctions emitted from radioactive sources are spherically symmetric, cloud chambers consistently record straight-line tracks. Standard explanations rely on decoherence, probabilistic branching, or implicit classical assumptions, yet none fully resolve how directional trajectories emerge from an initially isotropic quantum state. This paper presents a geometric interpretation of the Mott problem within the Dimensional Evolution (DE) framework, in which wavefunction collapse is treated as a resonance- and identity-mediated geometric process rather than a purely probabilistic event. Measurement is modeled as a structured interaction between system and detector identity wells, producing directional collapse funnels that anchor sequential localization events. Trajectory formation is described as a process of coherent tether crystallization, whereby successive measurement interactions align collapse curvature along a stable resonant direction. Straight tracks arise not from classical particle paths, but from the geometric reinforcement of collapse orientation through detector–system coupling. Inverse-domain resonance matching replaces environment-driven decoherence as the primary mechanism governing localization. The DE approach resolves the Mott paradox without invoking hidden variables, many-worlds branching, or ad hoc classical transitions, and provides a unified geometric explanation for trajectory emergence in quantum measurement systems. Implications for quantum foundations, measurement theory, and experimental testability are discussed.

Dimensional Evolution — Quantum Measurement and Identity Formation: A Geometric Framework for Wavefunction Structure, Collapse, and Probability

Charles A. S. Young

This paper presents Dimensional Evolution — Quantum Measurement and Identity Formation (DE-QM), a geometric framework addressing the quantum measurement problem while preserving the full predictive structure of standard quantum mechanics. Within DE-QM, the wavefunction is treated as a resonance-geometry field rather than a probability amplitude. Superposition arises from deterministic traversal across multiple resonance-compatible configurations supported by an inverse domain, rather than from the coexistence of mutually realized states. Measurement collapse is described as a geometric stability transition governed by anchoring thresholds imposed by environmental and detector constraints. Probability emerges as a derived measure of geometric overlap between scan traversal and detector geometry, recovering the Born rule without introducing intrinsic randomness or observer-dependent postulates. The framework integrates decoherence, entanglement, and relativistic structure into a unified geometric description that remains fully compatible with nonrelativistic and relativistic quantum mechanics, including the Schrödinger and Dirac formalisms. Entanglement is treated as a shared inverse-domain resonance geometry, enabling coordinated collapse without superluminal signaling. Measurement outcomes are shown to be observer-independent and physically grounded in macroscopic anchoring geometry, consistent with established experimental results. This manuscript serves as the foundational quantum-mechanical component of the broader Dimensional Evolution framework and builds directly on prior canonical works, including the DE Core paper, companion papers CP1–CP5, and specialized studies addressing the Mott problem and Dirac structure. DE-QM does not modify quantum mechanics’ mathematical formalism; rather, it provides a coherent geometric ontology underlying wavefunction structure, superposition, collapse, and probability. --- Project website: https://de-theory.com This work is part of the Dimensional Evolution research program.

The Mott Problem as a KnoWellian Rendering Cascade: An Ontological Solution from Procedural Field Theory

David Noel Lynch

This paper presents an ontological solution to the Mott problem, a foundational paradox in quantum mechanics concerning how a spherically symmetric wave function (e.g., from an alpha particle) produces a single, linear track in a classical detector. While Sir Nevill Mott's 1929 mathematical solution is complete, this work addresses the remaining philosophical unease by proposing a physical mechanism that selects a single classical path from an infinity of quantum possibilities. The solution is grounded in the KnoWellian Universe Theory (KUT), a framework built on procedural metaphysics. We posit that the formation of a particle track is not a wave function collapse but a KnoWellian Rendering Cascade—an irreversible, sequential transformation of potentiality into actuality. This process is governed by the KnoWellian Resonant Attractor Manifold (KRAM), a dynamic memory substrate of the cosmos. A modified Bohmian (pilot-wave) mechanic is proposed, where the particle's pilot-wave (identified as the Chaos Field in KUT) physically "etches" a directional "imprint" onto the local KRAM geometry upon the first rendering event (ionization). This imprint creates an attractor valley that makes subsequent rendering events along the same vector path overwhelmingly probable. The linear track is thus re-framed not as a "miraculous" alignment of probabilities but as a deterministic cascade causally guided by the memory of its own becoming. This framework provides a physical mechanism for the phase correlations in Mott's original solution and offers a new, testable foundation for understanding the quantum-to-classical transition.

The Dirac Equation: Resonance Geometry and Relativistic Quantum Identity

Young, Charles

This paper presents a geometric reinterpretation of the Dirac equation within the Dimensional Evolution (DE) framework. Without modifying the mathematical structure or empirical predictions of relativistic quantum mechanics, the Dirac equation is reformulated as a constraint on relativistic identity formation rather than as a purely kinematic wave equation. In this interpretation, the Dirac spinor encodes internal resonance structure required for relativistic coherence, while gamma matrices act as directional collapse operators mediating between internal geometry and spacetime constraints. The intrinsic doubling of solutions is explained as a structural duality between verse-domain localization and inverse-domain harmonic support, providing a physical account of antimatter without violating CPT symmetry or energy positivity. Spin, Zitterbewegung, and relativistic measurement are reinterpreted as consequences of resonance geometry rather than unexplained algebraic features. Measurement and localization are treated as local geometric stabilization processes consistent with Lorentz covariance, extending the collapse-geometry account developed in DE-SP6 (Mott) to relativistic systems. This work is interpretive and foundational in scope. It preserves full compatibility with quantum field theory and established relativistic quantum mechanics while clarifying the physical meaning of the Dirac equation’s most enigmatic structures. --- Project website: https://de-theory.com This work is part of the Dimensional Evolution research program.

Observation as Resonant Selection: A Physical Mechanism for Wavefunction Collapse

Charles Young

The quantum measurement problem — the question of what physically occurs when a quantum system yields a definite outcome upon measurement — has remained unresolved since von Neumann's formalization of quantum mechanics in 1932. Existing interpretational frameworks each address aspects of this problem while leaving a specific mechanistic gap unfilled. The Copenhagen interpretation declares collapse without explaining it. The many-worlds interpretation removes collapse but cannot specify the preferred measurement basis. Pilot wave theory identifies a guiding field without identifying what it is. Relational quantum mechanics correctly describes the relational structure of measurement outcomes without specifying the physical process by which relational facts are established. Decoherence theory specifies which outcomes are available through environmental selection without explaining which outcome actually occurs. In each case the effect of measurement is described with precision while the mechanism remains absent. This paper proposes that the Dimensional Evolution geometric framework provides that mechanism. Wavefunction collapse is resonant selection — the stabilization of a specific harmonic configuration when an observer's resonance structure synchronizes with a quantum system's scan traversal through a completed entropic pathway. This is not a metaphysical claim. It is a physically grounded geometric process from which the measurement postulates of standard quantum mechanics emerge as derived consequences rather than foundational axioms. The Born rule reflects the fractal exponential geometry of the coherence manifold. The preferred basis is geometrically specified by observer-system resonance compatibility. The measurement cut dissolves into a continuous spectrum of resonance stability requiring no quantum-classical boundary. The definite outcome problem is resolved by resonant synchronization completing — a deterministic geometric event whose apparent randomness reflects incomplete knowledge of resonance conditions rather than fundamental indeterminacy. The paper maps DE's resonant selection mechanism against each major interpretation, identifying precisely where DE does explanatory work each interpretation cannot. Three testable experimental predictions are proposed — geometry-dependent collapse timing, resonance-bandwidth-dependent outcome distributions, and a geometric memory effect in measurement apparatus — each grounded in physical principles confirmed at other scales and each distinguishable from standard quantum mechanical and decoherence predictions. The implications of this account for the Heisenberg uncertainty relation are identified as a priority for subsequent formal development.

The Mott Problem and Substrate Nucleation: A Fabric Framework Resolution

Zelenka, David D.

We present a resolution to the Mott problem (the apparent paradox of spherical quantum waves producing linear particle tracks) within the Fabric substrate framework. We propose that the wave function represents coherence patterns in a universal memory field M(x,t), and that particle detection corresponds to threshold-activated nucleation cascades in this substrate. The mechanism naturally explains track formation, straightness, and decoherence without invoking wave function collapse or many-worlds branching. We derive the nucleation dynamics, establish testable predictions distinguishing this interpretation from standard quantum mechanics, and connect the framework to agency and beauty as fundamental principles.

The Mott Problem: a spherically symmetric emission that records as a straight track

James Norman Ibbotson

An alpha-emitting nucleus is spherically symmetric and has no preferred axis. Quantum mechanics therefore describes the emitted alpha particle as an outgoing spherical wave of uniform angular amplitude, . Yet every cloud-chamber photograph of such an emission records a single straight track. This is Mott's problem (1929), the measurement problem in its sharpest experimental form: an apparent contradiction between a symmetry and a photograph. This paper (i) states the problem precisely, (ii) reproduces Mott's resolution quantitatively from CODATA constants — the alpha de Broglie wavelength, the angular tolerance set by the size of the recording atom, the resulting sideways wander over a finite track, and a direct numerical simulation of the joint alpha–atom amplitude that recovers the closed-form width, and (iii) examines a candidate interpretive model drawn from the Temporal Dynamics Framework and reports, on that model's own quantitative assumptions, that it adds no measurable prediction to Mott's result. This last outcome is recorded as a null, and a numerical target for any future derivation is fixed: rad for a 5.407 MeV alpha in hydrogen, equivalently a lateral wander of 1.86 m over a 10 cm track. No result here improves on Mott (1929); the solution is his. The contribution of this paper is a fully numerical restatement of that solution and an explicit, falsifiable target that fixes what any interpretive model would have to reproduce. This record holds one paper on its own and is refreshed every couple of months. The complete deposit, 10.5281/zenodo.21788037, holds every paper with its code and data and is updated first; for the newest version of this paper, go there.
