Discrete energy-level structures in Coulomb-like localized bound states are conventionally obtained by direct diagonalization of the Schrödinger equation or by semiclassical approximations that fail at low energies. Here we develop a geometric phase-space framework that recovers the exact discrete energy levels and shell degeneracy of three-dimensional Coulomb bound states from classical symplectic geometry and global boundary constraints, bypassing explicit operator diagonalization. Using Kustaanheimo--Stiefel regularization, we map negative-energy Kepler orbits to four-dimensional isotropic harmonic oscillators. The group composition law of the symplectic flow determines an integral kernel built from the classical two-point action and Van Vleck amplitude, whose infinitesimal generator satisfies an exact linear evolution equation---a property we term \textit{quadratic closure}. Imposing three geometric constraints---decay at infinity, regularity at the origin, and fiber invariance under the Hopf fibration---we recover the exact $E_n/E_1=1/n^2$ scaling and $g_n=n^2$ degeneracy. The phase scale $α$ sets the action unit; all spectral structural features are independent of its value. This framework offers a symmetry-transparent route to spectral data: for quadratic Hamiltonians, the classical kernel incurs zero semiclassical error even at ground-state energies, and the geometric constraints directly identify symmetry-protected degeneracies without diagonalization. We apply the method to shallow impurity states, moiré superlattices, and semiclassical transport, demonstrating how geometric screening rules simplify spectral analysis in condensed-matter environments.

Exact normalizable solutions of quantum constraints form a symplectic submanifold of the space of rays, whereas classical first-class constraints define a surface on which the symplectic form is degenerate. We ask how the degenerate directions can be recovered when quantum theory is regarded as fundamental and the constraints are imposed through a single positive master operator. For a nonnegative master function whose zero set is a Morse--Bott critical manifold, the image of the linearized Hamiltonian vector field is the symplectic orthogonal of the zero set, and coisotropy is equivalent to this linearization having square zero. The image is fixed by the zero set, but the theorem identifies it with the response of the master dynamics, which makes it accessible to quantum states. Three realizations follow. The exact quantum physical space is the opposite, rotational case of the same dichotomy. For quadratic masters, the bottom of the spectrum is $(\hbar/2)\Tr_+L$, so first-class zero sets carry no offset of order ℏ; within the harmonic approximation this explains the ℏ versus ℏ2 offsets observed in tests of the master-constraint programme. Finally, the second time derivative of the limiting covariance of a semiclassical packet, which can be determined by bounded probes, has the gauge distribution as its image. Two oscillators at fixed total energy give exact master evolution, an exact realization of this covariance shear, and the reduced symplectic limit. For the non-Abelian SL(2,R) model we compute the coherent and Weyl master symbols, prove essential self-adjointness and a finite-time propagation estimate, and derive the spectral bottom ℏ2/2.
Symplectic quantization is a functional approach to quantum field theory that allows sampling of quantum fluctuations directly in Minkowski space time by means of a generalized Hamiltonian dynamics in an extra time variable τ which, at large times, samples a microcanonical ensemble. In a previous work we showed that, for an interacting scalar theory in 1+1 dimensions, this framework captures genuine real time features that are inaccessible to Euclidean simulations. That original formulation suffers from two structural limitations, an ill defined non interacting limit and the lack of a direct correspondence between its correlation functions and those generated by the Feynman path integral. To solve these problems we introduced constrained symplectic quantization, a holomorphic reformulation in which fields and action are analytically continued and constraints are imposed on the intrinsic time Hamiltonian flow. The constraints select stable deterministic trajectories and they define convergent holomorphic integration cycles for the corresponding microcanonical measure. In the continuum limit we establish exact equivalence with the Feynman path integral at the level of the generating functional, thus providing a direct link between intrinsic time correlators and real time Green functions. In this contribution, we apply the method to the quantum harmonic oscillator on a real-time 1-dimensional lattice. Testing various observables, we find agreement between numerical and exact results for one- and two-point functions, and we reconstruct characteristic real-time features such as an oscillatory propagator, the discrete energy-gap spectrum, and the evolution of eigenstate probability densities. These tests provide numerical evidence that constrained symplectic quantization can sample real-time quantum observables and offers a practical route beyond Euclidean-time importance sampling.

The constraints select stable deterministic trajectories already for the free theory and they define convergent holomorphic integration cycles for the corresponding microcanonical measure. In the continuum limit we establish exact equivalence with the Feynman path integral at the level of the generating functional, thus providing a direct link between intrinsic time correlators and real time Green functions.

This work resolves a foundational tension in Dirac's formulation of relativistic quantum mechanics: momentum appears in two distinct but undifferentiated roles—as a dispersion-locked parameter generating unitary evolution in the relativistic wave equation, and as a free phase variable subject to symplectic flow in the constraint formalism. We demonstrate that this duality reflects an intrinsic Lorentzian structure in energy-momentum space, characterized by the interval dΣ² = dE²/c² − dp². This geometry divides naturally into three sectors: symmetric (dispersion-locked), null (massless, E/|p| = c), and antisymmetric (free-momentum) regimes, each governed by different geometric constraints. Dispersion emerges as the global integral of an exact action one-form, while the (E,p) symplectic structure arises locally as the exterior derivative of the action's inexact form θ_E = E dp. Energy quantization appears as a topological stability condition requiring closed spectral loops to satisfy ∮ E dp = nh, defining "proto-eigenstates" whose Fourier encodings yield standard Hilbert-space eigenstates. We recover both the Bohr spectrum and Dirac fine-structure energies from spectral phase closure, revealing α = e²/(ℏc) as a geometric action-normalization ratio between Maxwell U(1) curvature and Lorentz spinor action—not a coupling parameter from QED perturbation theory. The framework synthesizes unitary flow and symplectic uncertainty into a single bilinear Lorentzian structure, showing quantum states as objective in their symmetric unitary existence but path-dependent in their antisymmetric observed manifestation. This geometric reconstruction bridges Dirac's wave mechanics and constraint formalism through native (E,p) phase space, offering a foundation for quantum theory that treats energy-momentum as primary coordinates rather than conjugate variables derived from spacetime position.
Abstract We establish a complete geometric reconstruction framework in which quantization, symplectic structure, and infrared curvature emerge from the discrete phase overlaps between low-energy eigenstates of the spectral vacuum Hessian H. This work provides a rigorous derivation of Planck's constant ℏ as a measurable geometric quantity rather than a fundamental postulate. Key Results: 1. Emergent Symplectic Structure: From discrete phase overlaps θₐᵦ = arg⟨ψₐ|ψᵦ⟩, we construct a closed, non-degenerate 2-form: ω = Σ_{⟨ab⟩∈𝒩} (dθₐᵦ ∧ dλₐ) / √(ΔₐΔᵦ) satisfying the symplectic condition dω = 0 and rank(ω) = 2n, providing the first principles derivation of Hamiltonian dynamics from spectral data. 2. Geometric Origin of ℏ: We prove that Planck's constant emerges as the minimal symplectic area of a phase-space cell in the reconstructed manifold: ℏ ≈ ∮_{∂Σ} θₐᵦ dλ ≡ Area_ω(cell) linking quantization to the topological density of the spectral graph. 3. Topological Phase Invariants: We demonstrate that the discrete phases θₐᵦ converge to the Berry curvature and the Aharonov-Bohm phase shift in the continuum limit, where the magnetic flux is recovered as a spectral holonomy: Φ_AB = ∮_Γ 𝒜_Berry · dl establishing the framework as a discrete U(1) gauge theory on eigenvalue space. 4. Infrared Curvature Scaling: We show that the spectral gap Δ of the vacuum Hessian dictates the large-scale (IR) curvature of the emergent manifold: R_curv ~ 1 / √Δ offering a natural resolution to the infrared divergence problem and linking the cosmological constant to spectral stability. 5. Phase-Space Crystallization: We introduce the concept of Phase-Space Crystallization: quantization as a phase transition from continuous (classical) to discrete (quantum) phase space, with the spectral gap Δ acting as the order parameter: Δ = 0 → ℏ_eff = 0 (liquid/classical) Δ > 0 → ℏ_eff > 0 (crystal/quantum) exhibiting critical scaling ℏ_eff ~ (τ - τ_c)^(1/4) near the transition, where quantum mechanics emerges as the 'solid phase' of spectral geometry. Verification and Implementation: The framework is verified via a Discrete Exterior Calculus (DEC) pipeline through 10-seed Monte Carlo simulations confirming: • Symplectic closure: |dω| < 10⁻¹⁴ (machine precision) • Phase coherence: ⟨|δθ|⟩ < 10⁻³ • ℏ_eff stability: σ/⟨ℏ_eff⟩ < 5% • IR residual: R_IR/R* = 1.02 ± 0.02 with full Python implementation provided for reproducibility. Significance: This work completes the SVM foundation by showing that: • Quantization is geometric, not axiomatic • Planck's constant ℏ is a derived quantity from phase overlap structure • Symplectic geometry emerges from Berry phase curvature • Gauge theory (U(1)) arises from spectral holonomy (Aharonov-Bohm equivalence) • Quantum mechanics is a 'crystalline phase' of spectral geometry thereby unifying quantum mechanics, gauge invariance, and emergent gravity under a single spectral principle, with no external postulates.

STATUS: EXPLORATORY HYPOTHESIS (superseded by DOI: 10.5281/zenodo.18141753) - Emergent Coulomb Potentials and Orbital Quantization via Classical Dynamics on S3-Hopf Fibrations
The reconciliation of General Relativity (geometric determinism) and Quantum Mechanics (probabilistic indeterminism) remains the central challenge of modern physics. This paper presents a computational framework where fundamental quantum phenomena emerge from strictly deterministic dynamics in a 4-dimensional hyperspherical manifold (S3). We demonstrate that a classical harmonic oscillator confined to S3 geometry and projected onto R3 via the Hopf Fibration naturally reproduces the dynamics of a 1/r Coulomb potential. Numerical validation using a 4th-order Runge-Kutta integrator reveals a Virial Ratio of ⟨T⟩/⟨V⟩≈0.500, consistent with hydrogen-like systems. Furthermore, the introduction of an action-based phase condition (De Broglie relation) results in the emergence of discrete topological structures indistinguishable from Schrödinger’s probability orbitals. These findings suggest that the probabilistic nature of the wavefunction may be an artifact of projecting higher-dimensional geometric trajectories onto lower-dimensional space.
