The Pauli exclusion principle is traditionally introduced in quantum mechanics as a postulate encoded in the antisymmetry of the fermionic wavefunction. While extraordinarily successful, this formulation leaves open a deeper question: why must nature forbid the perfect overlap of identical fermions? In this work, we propose a reinterpretation of Pauli exclusion within the framework of Viscous Time Theory (VTT), where physical law emerges from the geometry of informational state space under constraints of memory, recoverability, and causal trace preservation. We propose that the coincidence of two identical fermionic states can be interpreted, in informational-geometric terms, as a loss of injectivity of the causal mapping, i.e., to an informational singularity where distinct histories become non-separable. To prevent this collapse of recoverability, the joint state manifold naturally develops a “diagonal barrier”: a forbidden submanifold where the informational cost diverges and admissible trajectories are repelled. Within this perspective, antisymmetry of the wavefunction appears not as the cause of exclusion, but as its mathematical symptom. Within this perspective, Pauli exclusion can be interpreted as a geometric and informational constraint rather than a primitive quantum axiom. The framework further suggests a unified interpretation of the difference between fermions and bosons: the former may be viewed as carriers of identity-bearing, non-overwritable informational structure, while the latter correspond to additive excitations that do not threaten causal injectivity. In this way, the exclusion principle appears as a consequence of informational geometry in a universe characterized by viscous time and memory.
Repulsive phenomena occupy a central place in the structure of the physical world, yet the foundations of repulsion remain poorly understood. The Pauli exclusion principle prohibits fermions from occupying identical quantum states but offers no ontological reason for why such overlap is impossible. Similarly, Coulomb’s law asserts that like charges repel, but the sign and direction of the interaction are inserted into electromagnetic theory rather than derived from deeper principles. In this paper, a unified structural account of repulsion is developed using the Structural Unified Field (SUF) framework, which treats physical entities as layered existence structures required to maintain minimal separability across attribute domains. The non-overlap axiom states that distinct entities cannot project into overlapping configurations without collapsing their structural identity. We show that Pauli exclusion arises from non-overlap in quantum-state space, while Coulomb repulsion emerges from non-overlap in the electrostatic domain. Spatial impenetrability, interatomic repulsion, and degeneracy pressure are likewise interpreted as manifestations of the same structural constraint. This structural ontology reframes repulsion as neither a force nor an axiomatic rule but as a universal consequence of identity preservation. The approach clarifies long-standing foundational issues concerning indistinguishability, the spin–statistics connection, the nature of quantum forces, and the role of structure in physical law. By grounding repulsion in a single ontological principle, the SUF framework provides a conceptually unified basis for diverse repulsive phenomena and suggests new directions for foundational research in quantum mechanics, electromagnetism, and the philosophy of physics.
Abstract This work develops a unified mathematical framework in which the fundamental principles of quantum mechanics arise naturally from the operator–topological structure of χ‑substance within the ZEBTS theory. The uncertainty principle, complementarity, the Pauli exclusion principle, entanglement, decoherence, and quantum measurement are reformulated in terms of χ‑operators, χ‑entropy, and topological transitions T^χ. Quantum dynamics is derived from the evolution of χ‑substance under the action of the fundamental operator D̂, with the Schrödinger and von Neumann equations appearing as projections of the general χ‑evolution equation. The theory introduces flightron dynamics, a new class of resonance phenomena capable of modifying coherence, entanglement, and conservation laws. Conservation principles and gauge symmetries are generalized to χ‑gauge transformations and topological invariants such as Chern numbers and Hopf indices. The resulting framework provides a coherent interpretation of quantum phenomena, resolves conceptual paradoxes such as nonlocality and wave‑function collapse, and predicts new effects including χ‑oscillations, flightron‑induced anomalies, and topological quantum transitions. Experimental strategies are proposed across ultracold atoms, quantum optics, condensed matter, high‑energy physics, and cosmology. ZEBTS thus offers a unified topological–operator foundation for quantum physics and opens a path toward a new synthesis of matter, geometry, and information.
Two of the most fundamental structural features of quantum mechanics — the Heisenberg uncertainty principle and the Pauli exclusion principle — are standardly treated as posits: brute facts about the physical world that quantum theory describes but does not explain. This paper argues that both receive principled ontological grounding from Constraint Theory (CT), the thesis established by transcendental argument that constraint is the ontological primitive constitutive of determinate existence as such. On the CT account, determinate physical entities are constituted by their constraint profiles — the specific exclusion relations that individuate them from everything they are not. The Heisenberg uncertainty principle is shown to reflect the conjugate structure of quantum constraint topology: position-space constraint and momentum-space constraint are dual expressions of a single underlying constraint structure, related by Fourier duality, such that closing one dimension of possibility space structurally requires opening the conjugate dimension. The Pauli exclusion principle is shown to be the direct physical expression of CT’s foundational claim that to be is to exclude: fermions are individuated through mutual exclusion, and the impossibility of two fermions occupying the same quantum state is the ontological requirement that distinct entities must differ in their constraint profiles. The fermion/boson distinction is given a unified structural interpretation: fermions are entities individuated by state-exclusion; bosons are entities whose mode of individuation does not proceed through state-exclusion. The paper engages the principal interpretive positions in the philosophy of quantum mechanics and the literature on quantum particle individuality, and argues that the CT account provides explanatory depth that these positions presuppose but do not supply.
The Pauli Exclusion Principle and the Spin-Statistics Theorem from Worldline Non-Injectivity: Exchange Phase, Rapidity, and Topological Sheet Structure For nearly a century, the Pauli exclusion principle (PEP) and the spin-statistics theorem have stood as foundational postulates of quantum mechanics and relativistic quantum field theory. The PEP dictates that no two identical fermions can occupy the same quantum state, determining the structure of atoms, the stability of matter, and the properties of neutron stars and white dwarfs. The spin-statistics theorem connects the intrinsic spin of a particle to its statistical behavior: half-integer spin particles (fermions) obey Fermi-Dirac statistics, while integer spin particles (bosons) obey Bose-Einstein statistics. Despite their universal success, these principles have never been derived from a more primitive geometric or topological principle — until now. This paper demonstrates that both the Pauli exclusion principle and the spin-statistics theorem emerge naturally and rigorously from a single geometric fact: the **non-injectivity of a timelike worldline** for Lorentz factors exceeding a critical threshold,
γ>γcrit. In this regime, a single worldline intersects a constant-time hypersurface
Σt in
N>1 distinct spatial points, generating a multi‑sheet spacetime structure. This phenomenon, known as **worldline non-injectivity**, is the foundation of the TPST–DGQ framework. **Key results and logical flow:** 1. **Multi‑sheet structure for a single particle:** For
γ>γcrit, a particle's worldline produces
N(ϵ)∼ϵ−(d−2) topological sheets, each carrying the same physical properties (mass, charge, spin) via the Ontological Identity Principle. 2. **Composite worldline for two identical particles:** By combining two identical particles into a composite worldline in configuration space, we obtain a two‑particle sheet structure. Identical particles share isomorphic sheet structures, reducing the
N×N sheet pairs to
N independent pairs. 3. **Exchange as a permutation of sheet blocks:** The exchange operator
P12 swaps the sheet blocks associated with the two particles. This permutation is a topological operation in the two‑particle configuration space. 4. **Exchange phase from winding number:** The exchange path corresponds to half of a complete winding cycle around the fold structure of the composite worldline. The accumulated topological phase is
Φexchange=πw, where
w is the **winding number** of the worldline. Hence the exchange phase factor is
η=eiπw=(−1)w. 5. **Spin from winding number:** The winding number
w is directly related to the spin
s by the requirement that a
4π rotation returns the physical state to itself (single‑valuedness). This yields
w=2s. Therefore
η=(−1)2s: half‑integer spin gives
η=−1 (fermions, antisymmetric), integer spin gives
η=+1 (bosons, symmetric). This is the spin‑statistics theorem derived from geometry. 6. **Pauli exclusion principle:** For two identical fermions (
η=−1) at spatial coincidence, the two‑particle amplitude satisfies
A=ηA, forcing
A=0. Thus no two fermions can occupy the same quantum state. The PEP is no longer a postulate; it is a theorem. 7. **Rapidity as inter‑sheet phase measure:** The rapidity
ζ=artanh(v/c) is shown to be a monotonic function of the inter‑sheet phase difference
Φn. The non‑injectivity threshold
γ>γcrit corresponds to
ζ>ζcrit. The speed of light
c emerges as the asymptotic limit where the inter‑sheet phase diverges, making
v=c unreachable for massive particles. 8. **Universal cancellation identity:** The same algebraic identity
N(ϵ)⋅ϵd−2=O(1) that regularizes holographic entropy, Coulomb self‑energy, wavefunction normalization, electromagnetic fields, and the cosmological constant also regularizes the two‑particle exchange amplitude — zero for fermions, finite for bosons. Quantum statistics thus joins the list of phenomena unified under the principle of worldline non‑injectivity. **Implications:** This work completes the derivation of the foundations of quantum mechanics within the TPST–DGQ framework, following previous derivations of the Born rule, the Schrödinger equation, Planck’s constant, and wavefunction collapse. It also establishes a geometric origin for the spin‑statistics connection, a result that in standard physics relies on the heavy machinery of relativistic quantum field theory (unitarity, causality, positivity of energy). Here, it follows from the topology of worldline folds. This manuscript is current in Official Peer Review. Not final version.Copyright©2026 Alex De Giuseppe.All rights reserved.

We derive Pauli exclusion as a geometric theorem inside Charlton Geometry, without assuming quantum antisymmetry as a postulate. The core primitive is the Charlton non-invertibility
ω∼−ω: the Lorentzian data induced by the Charlton Operator forgets the global polarity of the distinguished field
ω, producing a
Z2 ambiguity when lifting macroscopic symmetry loops into the spinorial representation.For two indistinguishable localized defects on a spatial slice, the configuration space
C2 has
π1(C2)≅Z2, generated by the exchange loop. Non-invertibility induces a polarity bundle over
C2 with two inequivalent holonomy branches: a trivial (``short'') lift with exchange phase
+1 (bosonic symmetry), and a nontrivial (``long'') lift with exchange phase
−1 (fermionic antisymmetry). On the long-lift branch, exchange realizes the nontrivial element of
π1(SO(3)), whose lift to
Spin(3)≅SU(2) terminates at the central element
−1, forcing
Ψ(x1,x2)=−Ψ(x2,x1) and yielding exclusion in the coincidence limit. We emphasize classification, not compulsion: Pauli exclusion is the geometric property of a stable topological branch, with defect-species placement addressed conditionally in later work.
