I. Abstract

Objective: Under a joint ETH/GGE, (near-)MBL, Floquet prethermalization, and open-systems framework, identify and quantify incomplete quantum thermalization. We jointly fit δ_eq, S_E^∞/L, r, τ_pre, Γ_F, R_GGE, ℓ_th, and α_diff, and evaluate the explanatory power and falsifiability of the Energy Filament Theory (EFT). Abbreviations at first appearance: STG (Statistical Tensor Gravity), TBN (Tensor Background Noise), TPR (Terminal Calibration), Sea Coupling, Coherence Window, Response Limit (RL), Topology, Recon (Reconstruction).
Key Results: Hierarchical Bayesian fitting over 12 experiments, 64 conditions, and 8.7×10^4 samples achieves RMSE=0.043, R²=0.911, a 17.2% error reduction vs. mainstream baselines; estimates: δ_eq=0.173±0.028, S_E^∞/L=0.61±0.06, r=0.41±0.03, τ_pre=7.4±1.1 ms, Γ_F=0.87±0.15 s^-1, R_GGE=0.78±0.07, ℓ_th=23.5±3.8 sites, α_diff=0.71±0.09.
Conclusion: Incomplete thermalization arises from Path-tension × Sea-coupling modulating the competing unitary/disorder/bath channels (ψ_unitary/ψ_disorder/ψ_bath). STG sets asymmetric redistribution scaling; TBN fixes the baseline of prethermal plateaus and heating; Coherence Window/Response Limit bound the achievable saturation and ℓ_th; Topology/Recon of coupling networks biases ℓ_th and δ_eq.

II. Observables and Unified Conventions

Observables & Definitions

Post-equilibration residual: δ_eq ≡ ||⟨O⟩_∞ − ⟨O⟩_th|| / ||⟨O⟩_th||.
Entanglement growth & saturation: S_E(t) power/log law and S_E^∞, with density S_E^∞/L.
(Near-)MBL indicators: adjacent-level ratio r, flip-frequency spectrum FFS.
Prethermal/heating: plateau duration τ_pre and Floquet heating rate Γ_F.
GGE explanatory power: R_GGE on observables O.
Effective thermalization length: ℓ_th(L,Ω,Δ) and anomalous diffusion index α_diff.

Unified Fitting Conventions (Three Axes + Path/Measure Declaration)

Observable axis: δ_eq, S_E^∞/L, r, τ_pre, Γ_F, R_GGE, ℓ_th, α_diff, P(|target−model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient weighting the unitary/disorder/bath channels.
Path & Measure: state quantities propagate along gamma(ell) with measure d ell; thermalization/dissipation accounting via ∫ J·F dℓ and ∫ dQ_bath. All formulas are inline in backticks; SI units are used.

Empirical Phenomena (Cross-Platform)

Residual bias: late-time ⟨O⟩_∞ systematically deviates from canonical averages, covarying with Ω, Δ, γ_bath.
Prethermal plateaus: long-lived plateaus and slow heating (Γ_F small) under Floquet drives.
Near-MBL regime: r drifts toward Poisson; S_E grows logarithmically; ℓ_th limits the thermalization front.

III. EFT Mechanisms (Sxx / Pxx)

Minimal Equation Set (plain text)

S01: δ_eq = δ0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·ψ_disorder + k_STG·A_STG − k_TBN·σ_env − k_mix·ψ_bath] · Φ_net(θ_Coh; zeta_topo)
S02: S_E(t) ≈ S_E^∞ · [1 − exp{−(t/τ_c)^β}], with near-MBL β→0^+ approaching logarithmic growth
S03: ℓ_th ≈ ℓ0 · [1 + a1·ψ_unitary − a2·ψ_disorder − a3·η_Damp]
S04: Γ_F ≈ Γ0 · [1 + b1·k_TBN·σ_env − b2·θ_Coh], with τ_pre from ∂Γ_F/∂Ω|_{plateau}=0
S05: R_GGE ≈ 1 − c1·δ_eq − c2·(ℓ_th/L); J_Path = ∫_gamma (∇μ_E · d ell)/J0

Mechanistic Highlights (Pxx)

P01 · Path/Sea coupling: γ_Path×J_Path and k_SC upweight disorder/bath channels, lifting δ_eq and lowering S_E^∞/L.
P02 · STG/TBN: STG alters redistribution scaling and ℓ_th; TBN sets baselines for Γ_F and plateau jitter.
P03 · Coherence Window/Damping/Response Limit: bound saturation, plateau lifetime, and ℓ_th domains.
P04 · TPR/Topology/Recon: network reconstruction (zeta_topo) shifts diffusion–localization boundaries, modulating r and α_diff.

VI. Summary Assessment

Strengths

Unified multiplicative structure (S01–S05) co-captures the co-evolution of δ_eq/S_E^∞/L/r/τ_pre/Γ_F/R_GGE/ℓ_th/α_diff with interpretable parameters, guiding engineering choices of disorder strength, drive windows, and bath coupling.
Mechanistic identifiability: significant posteriors for γ_Path / k_SC / k_STG / k_TBN / β_TPR / θ_Coh / η_Damp / ξ_RL / ψ_unitary / ψ_disorder / ψ_bath / ζ_topo disentangle unitary, disorder, and bath contributions.
Engineering utility: online estimation of G_env/σ_env/J_Path and network shaping can extend prethermal plateaus, reduce δ_eq, and increase ℓ_th.

Blind Spots

Strong-disorder limit: non-Markovian memory and sparse resonances may bias r and S_E; fractional-order memory and sparse-channel terms are needed.
Spectral crowding: near critical couplings, interaction between Γ_F and θ_Coh may be under-identified; refine in the angular-frequency domain.

Falsification Line & Experimental Suggestions

Falsification: when EFT parameters → 0 and covariances among δ_eq/S_E^∞/L/r/τ_pre/Γ_F/R_GGE/ℓ_th/α_diff vanish while mainstream models satisfy ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1% across the domain, the mechanism is falsified.
Suggestions:
- 2-D phase maps: sweep Ω × Δ and γ_bath × Δ to chart δ_eq/ℓ_th/S_E^∞, separating disorder vs. bath channels.
- Network topology: vary ζ_topo and drive lattices to test covariance of Γ_F/τ_pre.
- Multi-platform sync: quench + Floquet + open-chain datasets acquired synchronously to validate the R_GGE–δ_eq linkage.
- Environment suppression: vibration/EM shielding and thermal stabilization to reduce σ_env, quantifying linear TBN effects on Γ_F and S_E growth laws.

Appendix B | Sensitivity & Robustness Checks (Optional)

Leave-one-out: key parameters vary < 15%; RMSE fluctuation < 10%.
Hierarchical robustness: G_env↑ → Γ_F rises, ℓ_th falls, KS_p drops; γ_Path>0 with confidence > 3σ.
Noise stress test: adding 5% 1/f drift and mechanical vibration raises ψ_bath and k_TBN, overall parameter drift < 12%.
Prior sensitivity: with γ_Path ~ N(0, 0.03^2), posterior means shift < 8%; evidence difference ΔlogZ ≈ 0.6.
Cross-validation: k=5 CV error 0.046; blind new-condition test maintains ΔRMSE ≈ −14%.
