Paper 40: Coherence-Based Decoherence and Thermalization: Orbital Alignment and Collapse in the Holosphere Lattice

This paper presents an early Holosphere-theory model of decoherence, thermalization, and measurement. A localized quantum-like configuration (such as an electron analog) is treated as a triplet defect structure whose orbital channels stay stable only when their phase differences remain within a defined stability cutoff. Coherence is tracked using the SU(2) / S³ overlap baseline from Paper T33, with a clear separation between what is used for calibration (overlap and Born-type intensity) and what is claimed as new mechanism (thresholded stability loss under drift-driven diffusion). Thermalization is modeled as diffusion-driven broadening of orbital phase mismatch, controlled by the lattice-native coherence temperature TcohT_{\mathrm{coh}}Tcoh (identified with the Paper D calibrated effective temperature by convention). Decoherence time follows a first-passage estimate set by the cutoff and an effective diffusion coefficient, with a declared monotone scaling used for falsifiable predictions. Measurement is reframed as coherence locking to a macroscopic reference state, with directionality and effective irreversibility attributed to admissibility-limited transport and drift/diffusion constraints rather than stochastic projection. The paper concludes with concrete falsifiers, including threshold-squared scaling of coherence time, plateau behavior from stability bands, and correlations between drift-variance proxies and decoherence rates.
