Spin as Topological Holonomy and Collective Coherence in a Discrete Emergent Geometry

Short description A conceptual and minimally formal note within the ZM framework proposing that spin may be interpreted as a topological holonomy associated with finite oriented subgraphs of a discrete relational network, with collective coherence yielding effective classical fields and mesoscopic extensions of spin. Abstract We present a minimal discrete framework in which spin is not postulated as a fundamental quantum attribute but arises as a topological invariant associated with SU(2) holonomies on finite oriented subgraphs representing stable excitations of an underlying relational network. Each excitation is characterized by non contractible internal cycles whose holonomy encodes global phase memory. A fermionic sector is defined by minimal loops with holonomy −I, giving rise to the SU(2) to SO(3) double covering and the characteristic 4π behavior without invoking continuum geometry or intrinsic spin postulates. We further show that when gauge invariant phase coherence is established between neighboring subgraphs, internal holonomies become phase locked and extend over mesoscopic and macroscopic domains. In this regime, spin ceases to be a purely local property and acquires the status of a collective orientation field. Classical electromagnetic fields are interpreted as continuous limits of extended coherence domains of discrete holonomies. Minimal U(1) coupling reproduces the Pauli interaction with g = 2 at leading order, while deviations arise from holonomy fluctuations. The framework is compact, mathematically defined, and falsifiable, offering a unified interpretation of spin, its electromagnetic coupling, and the quantum to classical transition as consequences of discrete geometry and collective coherence. Description (EN) This record presents a discrete and relational interpretation of spin within the ZM research program. It examines whether spin can be understood as a topological holonomy associated with finite oriented subgraphs representing stable excitations of an underlying network, rather than as a primitive intrinsic quantum attribute. The note proposes that a fermionic sector is characterized by minimal cycles with holonomy −I in SU(2), thereby yielding the double covering SU(2) to SO(3) and the characteristic 4π structure without invoking background continuum geometry. It further argues that gauge invariant phase locking across neighboring subgraphs gives rise to collective coherence, effective orientation fields, and classical electromagnetic responses as coarse-grained limits of extended holonomy domains. The purpose of the present deposit is not to provide a complete dynamical derivation. It is to formulate a compact and falsifiable module within the broader ZM framework, clarify its conceptual scope, and define a structured basis for future formal and empirical development. Description complémentaire (FR) Ce dépôt présente une interprétation discrète et relationnelle du spin au sein du programme de recherche ZM. Il examine si le spin peut être compris comme une holonomie topologique associée à des sous-graphes orientés finis représentant des excitations stables d’un réseau sous-jacent, plutôt que comme un attribut quantique intrinsèque et primitif. La note propose qu’un secteur fermionique soit caractérisé par des cycles minimaux d’holonomie −I dans SU(2), ce qui fait émerger le double recouvrement SU(2) vers SO(3) ainsi que la structure caractéristique en 4π sans invoquer de géométrie continue de fond. Elle soutient également qu’un verrouillage de phase invariant de jauge entre sous-graphes voisins conduit à une cohérence collective, à des champs d’orientation effectifs, et à des réponses électromagnétiques classiques comme limites de coarse-graining de domaines étendus d’holonomies. L’objectif du présent dépôt n’est pas de fournir une dérivation dynamique complète. Il est de formuler un module compact et falsifiable dans le cadre plus large de ZM, d’en clarifier la portée conceptuelle, et d’établir une base structurée pour de futurs développements formels et empiriques. Scope and disclosure This record is a conceptual and minimally formal theoretical note within the ZM research program. It does not claim a complete derivation of the full quantum formalism, nor a finished microscopic dynamics. It introduces no implementation protocol, no engineering architecture, and no operational system design. All statements are formulated at the level of discrete structure, topological interpretation, admissible effective consequences, and theoretical scope.
