We develop a deterministic Hamiltonian route to finite-dimensional quantum mechanics as an infrareduniversality class. A stable real canonical system with a gapped positive-frequency sector admits a slow complexenvelope; resonant normal-form reduction produces an emergent U(1) action, fixing the projective state space toCP^(d-1), while quadratic moment maps generate u(d) and unitary infrared dynamics. The normalized positivequadratic effect gives the Born functional, and explicit Liouville first-passage/branch constructions providedeterministic single outcomes. Composite phase-space quantization yields the standard tensor-product quantumkinematics and singlet Bell correlations; deterministic Bell completion is necessarily relational rather than Belllocal. The present revision sharpens the microscopic claims. Geometric quantization of the fundamentalprojective representation selects the primitive action I0 = hbar. The scalar deformation g6(psi^dagger psi)^3 is aU(d)-singlet and produces no nontrivial Bell harmonic on the projective orbit. A genuine rank-3 moment-mapchannel would instead produce a P3(a dot b) correction with coefficient -R g3^2/(160 Omega3^2). Finally, literalmicroscopic UV uniqueness is shown to be underdetermined by operational data: invisible off-manifolddeformations and continuous families of autonomous relay realizations remain. The physically meaningfulmicroscopic target is therefore an operational equivalence class, with any stronger uniqueness claim requiringan additional UV selection principle. The paper also examines the primitive action scale and the microscopic completion. Compact symplectictopology gives an integral quantization condition and identifies the primitive sector I0 = hbar once that sector isselected. The microscopic relational construction uses an independent auxiliary doublet because the carriersector alone cannot supply the required composite relational structure. The resulting mechanisms close theeffective DQM construction while leaving the logically distinct empirical question of whether Nature is actuallydeterministic Hamiltonian mechanics.
Deterministic Quantum Mechanics (DQM) is a research program investigating whether the probabilistic content of quantum mechanics can be understood as an emergent statistical description of an underlying deterministic physical theory. This paper consolidates the program’s cumulative results into a single account.The central proposal is that a complete microscopic state evolves deterministically, that the quantum state is a coarse-grained ensemble descriptor rather than the complete physical state, and that measurement outcomes are selected by which deterministic basin of an enlarged phase space a microscopic trajectory occupies. Under this proposal, Born probabilities are basin measures rather than fundamental stochastic laws.For a qubit, this program is realized exactly: a hidden variable λ on the unit sphere, a preparation-dependent density μ_r(λ) = [r·λ]₊/π, and the deterministic response A(n,λ) = sgn(n·λ) reproduce the qubit Born rule P(±|r,n) = (1 ± r·n)/2 exactly, together with sequential-measurement statistics and the associated expectation values. This preparation measure is itself shown to be the deterministic pushforward of a uniformly distributed microscopic preparation coordinate, removing any appeal to fundamental preparation-level stochasticity.Measurement is then developed as deterministic basin selection within a finite-time Hamiltonian architecture, with a finite-time stability theorem governing when microscopic perturbations cannot dislodge a trajectory from its basin. Entangled correlations are reproduced by an autonomous, rotationally covariant Bell Hamiltonian containing dynamical setting registers and a conserved-momentum phase shear; this mechanism reproduces the singlet correlation E(a,b) = −a·b and the CHSH value 2√2 in its ideal limit, while preserving exactly uniform local marginals at finite setting inertia and yielding an explicit, quantitatively bounded finite-inertia correction. A finite Hamiltonian bath (Model-C) supplies a deterministic amplification and record-retention mechanism; its analytic structure — including an exact completed-square cancellation of the static bath backreaction and an exact finite-bath spectral equation — is derived independently of, and is shown to survive, a documented numerical implementation failure (the C14 program), which is retained in the record as a diagnosed, non-Hamiltonian right-hand side rather than as evidence against the underlying construction.Extending the program beyond the qubit exposes a genuine mathematical obstruction: no deterministic basin defined directly on the qutrit pure-state manifold ℂP² can reproduce an arbitrary rank-one Born probability, because positivity forces any exact basin onto a measure-zero point. This is proved rigorously. The resolution is not the abandonment of determinism but the enlargement of the hidden state beyond the quantum ray itself, to a genuine mechanical phase space such as the cotangent bundle T*SU(3), on which the quantum state re-emerges as a coarse-grained moment and on which contextual, Kochen–Specker-compatible measurement dynamics can in principle be realized.Throughout, the paper enforces a strict evidentiary hierarchy — mathematical construction, analytic theorem, numerical validation, and experimental confirmation are never conflated — and closes with an explicit account of what has been proved, what remains open, and what would be required to render the program experimentally falsifiable.
We reconstruct nonrelativistic quantum mechanics from exactly three physical axioms: microscopic ontic definiteness and finite localization, physical reality of the spacetime-vacuum substrate, and persistent causal source–response coupling. The single-run physical state is a finite topological core, its actual causal history, the substrate state, its sector, and the associated historical disturbance. A wave function is not identified with that ontic tuple. It is a ray in a Hilbert representation of admissible preparations and response amplitudes; a density operator is a statistical or reduced representation; and a record is a stable macroscopic event. The logical construction is acyclic. Finite-energy sector spaces and their continuous symmetry representations lead, under explicit representation conditions, to a complex Hilbert direct sum. A closed semibounded quadratic form defines the Hamiltonian and its self-adjoint realization. The standard Schrödinger action, unitary propagation, probability current, spectral observables, uncertainty relations, composite-system tensor products, spin representations, exchange sectors, instruments, and completely positive open dynamics then follow on their declared domains. Gleason-type reasoning fixes the Born form only after additivity, noncontextuality, continuity, and preparation–detector calibration are stated. Those operational conditions are not hidden physical axioms. The distribution of unresolved ontic initial data that realizes quantum equilibrium remains a realization certificate, not a theorem of topology alone. The Heisenberg representation is derived as a controlled transport of observables after Hilbert space and the self-adjoint generator have been constructed. Strongly continuous time translation, two-parameter nonautonomous propagation, common-domain Heisenberg equations, spectral matrix mechanics, regular Weyl relations, open-system adjoints, and instrument effects are connected by one certificate. Schrödinger and Heisenberg predictions are proved equivalent for one-time and finite instrument records, while finite-core, historical, truncation, domain, and detector errors remain separately bounded. Three frozen matrix benchmarks verify low-energy oscillator truncation and its state-weighted CCR defect, second-order unitary convergence for a driven doublet, Schrödinger–Heisenberg equality for a sequential instrument, finite auxiliary-history truncation, and quadratic leakage scaling for a conditional Dirac–Pauli interface. Independent reproduction, including the extended-precision audit, is closed for the frozen packet; physical coefficient calibration remains open. The next interface connects an owner-resolved Dirac–Pauli Hamiltonian to spin records through a Ward-compatible vertex, a causal passive history kernel, an independently audited doublet projection, SPAM-aware forward probabilities, nuisance-profiled identifiability, and a noncompensatory coefficient-to-record error theorem. The DPHC identifiability coordinate is executed on a frozen synthetic response family. A single-scale design is rank deficient, whereas an eighteen-setting frequency–gradient–order–time design has full profiled rank, controlled conditioning, near-nominal finite-sample coverage, and a calibrated held-out statistic. A robust twenty-setting design raises the worst registered information eigenvalue by
20.12%. A ten-parameter nonlinear audit exhibits an exact radiative–detector equivalence curve. An independent dark record breaks that symmetry and restores full local rank. Continuous-set robustness, validated global exclusion, and independent implementation are executed, while physical response identification and empirical calibration remain open. Measurement is treated as a dynamics of system, apparatus, environment, and actual history. Unitary premeasurement and decoherence select robust record sectors but do not by themselves select one record. The three-axiom ontology supplies one actual branch history, while a measurable response map from the complete initial state and instrument to the final record supplies the missing dynamical content. Bell correlations require contextual and nonfactorizable ontic response while parameter independence and operational no-signalling are retained; no controllable superluminal channel is introduced. Historical response produces causal non-Markov Hamiltonians and memory-kernel master equations. Their normalization, positivity, complete positivity, and energy ledger are derived from a unitary enlarged realization whenever such a dilation exists. Finite-core form factors and causal memory yield explicit departures from point-core Markov quantum mechanics. Standard quantum mechanics is recovered as the unresolved-core, sector-fixed, quantum-equilibrium, short-memory limit. Quantum field theory is retained as a successful local, spectral, and asymptotic calculus, but field operators, Fock vectors, and vacuum functionals remain effective representations until a noncircular map from finite carriers and their complete causal histories has been certified. The manuscript proves a sequence of previously open analytic, mathematical, measurement, topological, statistical, and computational obligations on explicitly declared domains. These include non-Markov diffusion, graph-norm stability, distorted-wave and pole variation, finite passive-memory realization, Fisher-information identifiability, detector pushforwards, unique-record basins, Born-representation bounds, measurement independence, topology–Dirac charge conjugation, Stern–Gerlach records, action-scale matching, rank-two spin projection, Finkelstein–Rubinstein topology, Clifford reconstruction, and parent-to-record realization maps. Eighteen groups of numerical obligations are executed on frozen reference models. They cover spectral and scattering calculations, oscillator and two-level dynamics, Schrödinger–Heisenberg equivalence, finite-history truncation, Dirac–Pauli and Foldy–Wouthuysen reduction, gauge covariance, interference, Bell and GHZ correlations, open-system memory, Stern–Gerlach records, identifiability, global searches, topological invariants, path products, semiclassical limits, partial-wave optical closure, the relativistic/QFT interface, and conservative-parent two-level dynamics. Every environment explicitly typed as a computational obligation now has an executed frozen-model certificate; empirical identification and separately typed experimental inputs remain open. The present manuscript differs so substantially from the earlier version in scope, logical architecture, proofs, and executable certificates that it is issued as a new upload rather than as a minor revision. Because the subject is both foundational and technically consequential, readers professionally engaged in quantum foundations, mathematical physics, quantum measurement, or related fields are encouraged to consult both versions: the earlier version preserves the developmental route, whereas the present version gives the substantially expanded and reorganized reconstruction. ## Keywords Axiomatic quantum mechanics; finite particle histories; retarded Green functions; Schrödinger equation; Dirac equation; Born rule; topological spin; quantum measurement; non-Markovian dynamics; classical limit.
Living Field Theory (LFT) proposes that physical structure is described fundamentally by a single real field together with constraints on its admissible histories. This paper investigates the emergence of quantum-mechanical structure within the coherent sector of that framework. A phase-active real coherent carrier equipped with a compatible positive quadratic form is shown to admit an effective complex structure and associated symplectic geometry without requiring a primitive complex field. Predictive equivalence under nonzero coherent scaling yields projective state geometry without requiring a dynamically selected universal fixed-action shell. Stable detector outcomes are represented by disjoint families of admissible Living-Field histories. Their weighted history measure is therefore additive under physical refinement. When the corresponding detector refinement occurs coherently before stable record formation, projective detector weights satisfy x=x1+x2x=x_1+x_2. Requiring a common continuous response law P=f(x)P=f(x) to remain consistent under such refinement gives f(x+y)=f(x)+f(y)f(x+y)=f(x)+f(y). Together with f(0)=0f(0)=0 and f(1)=1f(1)=1, this uniquely yields f(x)=xf(x)=x, giving the Born weighting rule Pi=∣⟨ei∣Ψ⟩∣2P_i=|\langle e_i|\Psi\rangle|^2 for normalized states and orthonormal detector channels. The work also distinguishes pre-record coherent refinement from post-record subdivision and examines several unsuccessful stronger emergence routes, including universal fixed-action-shell selection, norm preservation as sufficient for unitary dynamics, and derivation of Hamiltonian time evolution from a positive fluctuation Hessian alone. The result is a conditional derivation of Born weighting within the LFT coherent-sector bridge. It does not claim an unconditional derivation of quantum mechanics from the minimal Living-Field ontology. The remaining problem is localized to the primitive provenance of the required coherent carrier, compatible metric, detector-response structure, and accessible coherent refinements.
Action principles, phase accumulation and quantized closure appear across classical mechanics, quantum theory, semiclassical dynamics, superfluidity and geometric phase phenomena. Their coexistence is familiar; their structural relationship is usually taken as part of the established formalism. Here we reconstruct that relationship in the opposite direction. Starting from persistent relational dynamics, we show how a real two-component rotation supplies a phase coordinate without assuming a primitive complex number, how a relational canonical one-form can connect phase increments to action-like increments, and how stationary phase and global phase consistency impose two distinct selection conditions. The local condition yields stationary action, δA_R = 0. The global condition yields integral symplectic periods. Under the explicit convention F_R = −iΩ_R/κ_A for a U(1) connection curvature, global compatibility requires [Ω_R/(2πκ_A)] ∈ H²(M_R,Z), equivalently ∫_Σ Ω_R = 2πnκ_A on closed two-cycles. This separates the origin of discreteness from the origin of the dimensionful conversion scale. Topology fixes integer classes; it does not determine κ_A. We therefore identify a precise remaining problem: what selects a unique, universal and non-zero κ⋆ across coherently composable sectors? The framework makes this question falsifiable by requiring cross-scale closure, causal ancestry, intervention consistency and independence from observer compression. It also distinguishes a universal phase–action conversion scale from scale-dependent effective couplings. The result is a sharpened bridge from relational phase to stationary dynamics and quantized closure, with a mathematically explicit boundary between what is derived, what is inherited from established geometry, and what remains to be selected dynamically. The revision formalizes an Action-Scale Factorization Theorem together with Exact-Action and Curvature-Compatibility no-go results, thereby separating the existence of quantized closed-path sectors from the still-open physical selection of a universal non-zero scale such as ħ.
This study asks which structures can be derived from a single finite relational system to which no prior physical meaning, coordinates, or time are assigned. A selector-free relational lift and its minimal self-sustaining orbit generate an intrinsic separator order and grading, providing a directed order axis without an external clock. Boolean-diamond incidence defines transverse locality, and five-K4 incidence produces an exact S3 minimal persistent complex whose canonical continuation yields a four-dimensional associated realization. An explicit finite witness gives a nonzero commutator between longitudinal incidence and transverse locality, ruling out a simple product of fixed space with independent time. A complementary stable-quotient readout contains a refinement branch that closes as a one-dimensional metric-graph continuum. Combined with the S2 fiber of the standard S4 representation, this gives a regular spatial sector locally of the form (0,1) x S2(R). The S2 Laplace spectrum provides a branch-independent nonzero rest gap for every l >= 1; under the stated internal second-order wave representation this gap is read as a rest-mass parameter. Gravity is represented by an exact finite source-to-field map using the Moore-Penrose Green operator, and the regular three-dimensional branch yields the local 1/r^2 acceleration exponent in the weak-static regime. The same relational development also supplies three distinct internal Hilbert representations. Conditional on the full orthogonal-projector event structure and standard noncontextual probability consistency, Gleason's theorem fixes the Born form in the spatial representation. The incidence representation is noncommutative and yields the Robertson uncertainty relation, while procyclic reaction gives exact discrete unitary dynamics by Haar-measure invariance. No canonical identification of these Hilbert spaces, unique continuous Hamiltonian, measurement-update rule, spin-1/2 structure, or Bose/Fermi statistics is claimed.
