Book IV — Persistence is part of the Radial Coherential Dynamics (RCD) research program and focuses on the physical conditions under which coherence and order can persist in open systems subject to noise and dissipation. Building on cross-platform experimental results obtained in January 2026—where GHZ entangled states exhibited approximately 50% improved coherence retention across incompatible quantum hardware—this book introduces the concept of structural persistence: the idea that certain correlation geometries resist decoherence not by isolation or active correction, but by minimizing their entropic attack surface. The work reframes the central question from “How do we create coherence?” to “What kinds of coherence can survive?” and examines three interconnected elements:(i) empirical persistence thresholds (e.g., the observed ~99.5% fidelity threshold),(ii) thermodynamic openness via entropy sinks (including the cosmological horizon), and(iii) the role of state geometry in optimizing dissipation. No new experiments are presented. Instead, the book consolidates existing data, evaluates compatibility with established physics (Landauer’s principle, Gibbons–Hawking thermodynamics, Jacobson’s derivation of gravity), and explicitly delineates what is known, hypothesized, and not yet derived. Book IV does not claim a new theory of gravity, consciousness, or cosmology. It establishes a disciplined conceptual framework and a falsifiable research program, identifying open gaps and proposing concrete directions for future experimental and theoretical tests. This volume emphasizes methodological modesty: compatibility is not proof, but without compatibility, no path forward exists.

This work develops the conceptual and physical foundations of emergent causality and time within the framework of Radial Coherential Dynamics (RCD). It explores how relativistic structure, causal order, and effective temporal dynamics arise from a coherence-based description of quantum systems, emphasizing the role of decoherence, entanglement structure, and information flow. The document is intended as a theoretical monograph within the broader RCD research program, bridging foundational concepts and future experimental validation, without presupposing a fixed publication sequence.
This is the academically citable, open-access companion to the printed monograph "Enticuant: Book IX of the RCD 2.0 Program — Five Chapters on Coherence: Geometry, Thermodynamics, and Empirical Law" (Arturo Cerezo García, Quantum Benchmark Insights, May 2026, ISBN-13 979-8195474782). Book IX of the RCD 2.0 program (Radial Coherential Dynamics) introduces and consolidates a new conceptual term — the enticuant — and gathers five chapters that the program took two years to earn. Not by speculation. By measurement, by calculation, by verification across multiple independent quantum hardware platforms. The enticuant names what the coherential field C(x,t) becomes when it crosses from formal scalar to operational object: when its decoherence is organized by the Hamming distance, when its irreversibility is measured on real quantum machines, when its geometric counterpart in disformal gravity is bounded by mathematical theorem. Five chapters, five verbs: — RELOCATE: GHZ entanglement is moved from theoretical center to coherential limit (Chapter VI), based on a five-platform validation campaign on IBM Heron, IonQ Forte, Rigetti Ankaa-3, IQM Garnet, and IQM Emerald. — SITUATE: RCD is positioned with respect to the Standard Model (Chapter VII), declaring four explicit walls the program does not cross. — NAME: The Coherential Hamming Law (Chapter VIII), a transversal empirical regularity verified on five quantum architectures with statistical significance p ≈ 7×10⁻²⁷. — MEASURE: The first structured experimental measurement of the coherential component of irreversible entropy Ξ on commercial NISQ hardware (Chapter IX), with a six-point curve on IBM ibm_fez. — PROVE: A mathematical theorem of disformal subluminality with dust (Chapter X), demonstrating that the scalar sound speed in DHOST gravity is subluminal in any astrophysically relevant environment, with explicit GW170817 compatibility. Each chapter integrates a guest voice — Hamming, Heraclitus, Boltzmann, Newton, Lao Tzu, Vera Rubin, and others — acknowledging the program's debt to twenty-five centuries of rigorous thought. The complete book consists of: Threshold, Foreword, Prologue ("La Idea Antes de la Idea"), and ten integrated chapters (I — The Coherential Field; II — Coherential Perturbations; III — Gravitational Coupling; IV — The Enticuant; V — Geodesometry of Coherence; VI — GHZ as Coherential Limit; VII — Two Scalar Fields; VIII — Coherential Hamming Law; IX — Thermodynamics of Coherence; X — Geometry of Coherence). All raw experimental data referenced in the book is publicly deposited on Zenodo. The measurement remains the arbiter. Five chapters, five verbs: Relocate · Situate · Name · Measure · Prove. This Zenodo deposit makes the full text openly available under CC-BY 4.0 alongside the printed paperback edition, enabling academic citation, indexing in OpenAIRE, and integration into the broader RCD 2.0 program registry on Zenodo.
The Field That Learns to Look at Itself is Book X of the RCD 2.0 — Radial Coherential Dynamics — program. This English-language volume stands at the intersection of scientific essay, research notebook, philosophy of physics, and methodological audit of an independent research program in development. The book documents a critical stage in the RCD program: the transition from a broad intuition about coherence, time, and the emergence of structure toward a stricter formulation capable of distinguishing between metaphor, evidence, operationalization, hypothesis, prediction, and speculation. It does not present a closed physical theory or a final promise of unification. Its central purpose is to record the moment in which an idea learns to look at itself: to recognize its limits, separate its levels of discourse, and submit its claims to criteria of falsifiability. The central question running through the volume is whether coherence can function as a guiding concept for thinking about the transition between reversible quantum structure — phase, superposition, interference, and measurement — and the appearance of stable records, effective boundaries, ordered time, and macroscopic structure. Throughout the book, several meanings of the word “coherence” are examined, while warning against the risk of treating them as if they named a single physical object. In particular, the book distinguishes strict quantum coherence, GHZ population retention, thermodynamic witnesses, the effective field C, domain formation, operational coupling modulations, and coherence as a guiding idea or philosophical metaphor. This distinction becomes one of the technical and ethical axes of the volume: not everything that shares a word shares the same physics. The book also records an important internal correction of the RCD program: RCD should not derive gravity, spacetime, or fundamental cosmology directly from a late-time effective kernel. Instead, the volume proposes a more sober reading: preserve what has operational support, separate levels of evidence carefully, and keep open only those routes that can be formulated through observables, numerical predictions, and possible tests of refutation. As part of the public RCD record, The Field That Learns to Look at Itself serves a double function. On one hand, it preserves the conceptual and literary dimension of the research: the intuition that coherence, understood rigorously and without equivocation, may offer a way of thinking about the passage from reversible possibility to stable record. On the other hand, it functions as a methodological act: a warning against false confirmation, ambiguous language, improper transfer of evidence between sectors, and the temptation to turn a fertile analogy into an unproven physical identity. This version corresponds to edition 1.0 of Book X in English. It should be read as a companion volume to the Spanish edition and to the public set of RCD preprints, technical notes, and research records deposited on Zenodo, especially those related to quantum coherence, Allen–Cahn/Wright–Fisher effective kernels, operational influence fronts, OTOC, emergence of effective time, and adversarial audit of hypotheses.

Coherence First develops a relational reformulation of Radial Coherential Dynamics (RCD) centered on a prior question: what physically selects the factorization of a quantum system into subsystems? Because entanglement is defined only relative to a tensor-product structure or a partition of observable algebras, programs that derive classicality, locality, or geometry from entanglement already presuppose a cut. The paper proposes the Coherential Selection Principle (CSP): the physical factorization is the one that maximizes the persistence of coherent information within its parts while minimizing coherent persistence across their boundaries. In this framework, subsystems are dynamically persistent regions of a relational quantum structure, and the coherential field C(x,t)C(x,t) is reinterpreted as a possible continuous, effective description of a deeper network of selected relations. A numerical proof of concept is presented for an open three-qubit system. Keeping the Hamiltonian fixed while rotating the environmentally monitored algebra shifts the factorization favored by a provisional functional. The effect survives a generic non-commuting control, remains stable under sampling, and follows a continuous five-point rotation of the monitored algebra. The result establishes that open dynamics can transport and recover a recognizable structure of parts that is not fixed by the Hamiltonian alone. The full CSP, the emergence of geometric locality, and the proposed connection to cosmological relaxation remain the next stages of the program. Version 0.2. Preprint; not peer reviewed.
