Gravitational-Wave–Induced Coherence Effects in Extreme Regimes: A Phenomenological Exploration

This work presents a phenomenological exploration of coherence-related effects induced by intense gravitational-wave environments within the framework of the Unified Theory of Informational Spin (TGU). Rather than claiming observational detection or confirmed matter creation, the study investigates a hypothetical mechanism by which strong, non-linear spacetime perturbations may drive localized departures from linear gravitational regimes, giving rise to effective coherence gradients. A simplified toy model is introduced to describe how extreme gravitational-wave excitation could correlate with geometric indicators of regime validity, without modifying gravitational-wave propagation or source dynamics. The analysis is explicitly limited to exploratory regimes and does not assert direct correspondence with current gravitational-wave detections. Instead, it aims to assess internal consistency, qualitative behavior, and limiting properties of coherence-based diagnostics under sustained non-linearity. The framework is constructed to converge exactly to General Relativity in weak-field and linear regimes, while allowing controlled deviations only at the level of regime characterization. In this context, coherence indicators are shown to act as diagnostic tools that may signal inference degeneracies when standard linearized gravitational-wave templates are applied beyond their domain of validity. The phenomenological descriptors employed in this study are not introduced as independent model parameters, but are inherited as diagnostic proxies from the broader geometric framework of the Unified Theory of Informational Spin, where coherence-related quantities arise from fixed normalization conditions and vanish identically in linear gravitational regimes. The results motivate future, fully reproducible studies using public gravitational-wave datasets and provide a structured phenomenological basis for exploring regime-aware inference methods, without introducing exotic matter fields, modifying propagation laws, or violating established conservation principles (LIGO–Virgo–KAGRA Collaboration, 2023) [2].
