On the Regime-Limited Validity of Quantum Mechanics (IM-I002, v0.3)

Abstract

This document is part of the Informational Mechanics (IM) framework and is published in the IM-I (Reviews & Syntheses) series within the IM v0.3 corpus. The paper synthesizes recent IM work on universality and regime-limited validity to clarify the status of quantum mechanics under admissibility constraints. Rather than proposing modifications to quantum theory, it analyzes the conditions under which claims of global validity remain scientifically meaningful. Drawing on IM-C003 (regime-limited universality), IM-E001 (operator criteria for universality), and IM-D005 (structural non-derivability across regime transitions), the document shows how quantum-mechanical unitarity and state evolution must be understood as regime-bound statements whose validity depends on operator-defined implementability and cross-regime comparability. The paper introduces no new axioms, models, or empirical results. Its purpose is clarificatory and integrative: to provide a coherent account of how quantum mechanics retains full validity within admissible regimes while avoiding unwarranted global extrapolation beyond operator-defined structure.

Unitary Evolution Across Regime Transitions: Structural Non-Derivability Under Admissibility Constraints (IM-D005, v0.3)

Anders Nils Gunnar Widgren

This document is part of the Informational Mechanics (IM) framework and is published in the IM-D (Core Physics) series within the IM v0.3 corpus. The paper analyzes the status of unitary evolution when physical description crosses regime boundaries. While unitary time evolution is well-defined within admissible geometric regimes, its extension across inadmissible regime transitions is shown to lack structural derivability unless operator-defined state continuity can be physically implemented. Building on the regime-limited validity arguments of IM-C003 and the operator criteria formalized in IM-E001, the paper demonstrates that global unitarity cannot be presumed as an ontological default. Instead, unitary evolution must be treated as a regime-bound statement whose validity depends on the continued implementability of the operators required to define and compare physical states. The analysis introduces no new axioms, dynamical models, or empirical fits. Its contribution is structural: to clarify the admissibility conditions under which claims of global state continuity remain scientifically meaningful and to show why cross-regime extrapolations of unitarity constitute a category error when operator-access fails. Downstream empirical and simulation-based evaluation of regime transitions is addressed in the IM-G series.

Operator Status of the Wavefunction: Admissibility, Observables, and Regime-Defined Physical Content (IM-E003, v0.3)

Anders Nils Gunnar Widgren

This document is part of the Informational Mechanics (IM) framework and is published in the IM-E (Measurement & Operators) series within the IM v0.3 corpus. The paper analyzes the physical status of the quantum-mechanical wavefunction under admissibility constraints. Rather than adopting an ontological position (ψ-realism or ψ-epistemicism), the analysis evaluates when the wavefunction carries operator-defined physical content within a declared quantum-mechanical regime. Within Informational Mechanics, physical content is defined only where operator-implementable observables, stable invariants, and regime-bounded comparability are available. The wavefunction is therefore treated as a regime-defined representational object whose physical meaning depends on the continued admissibility of the operators required to define and compare its associated observables. The paper introduces no new axioms, collapse models, hidden variables, or empirical fits. Its contribution is structural and operational: to clarify when statements about the wavefunction are scientifically meaningful and when they extend beyond operator-defined structure.

Measurement Update as Operator Reclassification: A Regime-Conditional Account (IM-E005, v0.3)

Anders Nils Gunnar Widgren

This document is part of the Informational Mechanics (IM) framework and is published in the IM-E (Measurement & Operators) series within the IM v0.3 corpus. The paper analyzes quantum measurement update as an operator reclassification problem under admissibility constraints. Rather than introducing collapse dynamics or new axioms, the analysis formalizes the structural conditions under which outcome weights are uniquely determined by orthogonal additivity, invariance, and minimal regularity requirements. Building on the mathematical uniqueness result of IM-B002, the paper shows that admissible strength functionals compatible with operator-defined observables must take the squared-norm form within quantum-mechanical regimes. Measurement update is treated as a regime-bounded representational transformation rather than an ontological discontinuity. The work introduces no new axioms, collapse models, hidden variables, or empirical fits. Its contribution is operational and classificatory: it clarifies the admissibility conditions under which squared-amplitude outcome weights retain scientific meaning while preserving unitarity and operator-defined locality.

Entanglement as Structural Non-Factorizability: A Regime-Conditional Account of Bell Correlations (IM-D006, v0.3)

Anders Nils Gunnar Widgren

This document is part of the Informational Mechanics (IM) framework and is published in the IM-D (Core Physics) series within the IM v0.3 corpus. The paper develops a structural account of quantum entanglement under regime-limited admissibility constraints. Rather than introducing new dynamics, hidden variables, or collapse mechanisms, it analyzes entanglement as a consequence of structural non-factorizability arising from bilinear composition and tensor minimality within admissible operator regimes. Building on IM-B004 (tensor minimality), IM-C004 (regime-conditional structural principles), and IM-E004 (operator-defined outcome weights), the analysis shows that Bell-inequality violations constrain classical factorizability assumptions without implying superluminal signaling or ontological inseparability. The account preserves the formal structure of quantum mechanics and treats locality and no-signaling conditions as operator-level constraints. No new axioms, empirical fits, or modifications to established physical theories are introduced. The contribution is classificatory and structural: it clarifies how entanglement and Bell correlations emerge within regime-bounded admissibility while explicitly identifying the structural assumptions under which the account would require revision.

Operator Outcome Measures and the Squared-Norm Form: A Structural Admissibility Result (IM-E004, v0.3)

Anders Nils Gunnar Widgren

This document is part of the Informational Mechanics (IM) framework and is published in the IM-E (Measurement & Operators) series within the IM v0.3 corpus. The paper analyzes the structural status of outcome weights in quantum measurement under admissibility constraints. Rather than modifying quantum mechanics or deriving new dynamical laws, it formalizes the operator-defined conditions under which outcome weights must be proportional to the squared norm of state amplitudes. Building on the mathematical uniqueness result established in IM-B002, the analysis shows that orthogonal additivity, invariance under unitary transformations, and minimal regularity conditions constrain admissible strength functionals to the squared-norm form. The result is structural and regime-bounded: it applies within quantum-mechanical regimes where operator-defined observables and comparability are physically implementable. The paper introduces no new axioms, collapse models, hidden variables, or empirical fits. Its contribution is operational and classificatory, clarifying the admissibility conditions under which squared-amplitude outcome weights retain scientific meaning while avoiding unwarranted ontological extrapolation.

Operator Stability and Classical Emergence: A Regime-Based Criterion for Observable Invariance (IM-E002, v0.3)

Anders Nils Gunnar Widgren

This document is part of the Informational Mechanics (IM) framework and is published in the IM-E (Measurement & Operators) series within the IM v0.3 corpus. The paper formalizes an Operator Stability Condition (OSC) that specifies when quantum-mechanical observables exhibit regime-stable invariance under admissible disturbance. Rather than introducing new dynamics or modifying quantum theory, the analysis provides a structural criterion for when operator-defined quantities become persistently comparable and support classical description. Classical emergence is treated as a consequence of operator stability: when observables retain invariant content under admissible measurement and environmental interaction, effective classical structure arises without invoking collapse models, hidden variables, or additional ontological assumptions. The paper introduces no new axioms, dynamical mechanisms, or empirical fits. Its purpose is operational and disciplinary: to clarify the admissibility conditions under which classical description remains scientifically meaningful and to connect foundational admissibility constraints (IM-C series) with downstream structural consequences (IM-D series).
