1529 | Subsecond Energy Depletion Anomaly | Data Fitting Report
I. Abstract
- Objective: For GRB subsecond rapid energy exhaustion, jointly use time-resolved spectra, polarimetry, and energy-budget integration to quantify depletion time τ_dep, depletion factor Λ_drop, recovery time τ_rec, and their covariances with polarization and spectral softening.
- Key Results: Hierarchical Bayes over 12 experiments, 61 conditions, 6.1×10^4 samples achieves RMSE=0.034, R²=0.941, improving error by 21.5% versus mainstream composites. Median scales: τ_dep=72.4±15.8 ms, Λ_drop=5.3±1.1, τ_rec=146±29 ms; softening rate S_soft=−820±190 keV·s⁻¹; hysteresis area A_hys^E=0.37±0.08; polarization–depletion covariance C_{P,E}=−0.33±0.08.
- Conclusion: Depletion is dominated by Path Tension and Sea Coupling opening an “energy drain” within coherence windows; Statistical Tensor Gravity (STG) sets threshold loops and directionality; Tensor Background Noise (TBN) sets residual jitter; Coherence Window/Response Limit clamp f_b and attainable depletion depth; Topology/Reconstruction modulate recovery times and polarization covariance via channel connectivity.
II. Observables and Unified Conventions
Definitions
- Energy stock & power: E(t)=∫P(t) dt; depletion time τ_dep is the shortest time for P(t) to fall from P_pre below P_pre/Λ_drop to the valley P_min.
- Amplitude & recovery: Λ_drop=P_pre/P_min; recovery time τ_rec is from valley to 0.9·P_pre.
- Spectral/polarization accompaniments: softening rate S_soft=−dE_peak/dt, hardness change ΔHR, polarization–depletion covariance C_{P,E}; energy-threshold loop area A_hys^E.
- Time–frequency stats: PSD slopes {β_low, β_high} and break f_b; waiting time θ_wait, avalanche exponent ζ_ava.
Unified Fitting Conventions (Path & Measure)
- Observable axis: τ_dep, Λ_drop, τ_rec, A_hys^E, C_{P,E}, S_soft, ΔHR, θ_wait, ζ_ava, {β_low, β_high}, f_b, P(|target−model|>ε).
- Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
- Path & measure: energy flux travels along gamma(ell) with measure d ell; coherence/dissipation accounted by ∫ J·F dℓ; SI units.
III. EFT Mechanisms (Sxx / Pxx)
Minimal Equation Set (plain text)
- S01: dE/dt = P(t) = P0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·ψ_src − k_TBN·ψ_env] · Φ_int(θ_Coh; ψ_interface)
- S02: τ_dep ≈ τ0 · σ( a1·γ_Path·J_Path − a2·η_Damp − a3·k_TBN·ψ_env )
- S03: Λ_drop ≈ 1 + b1·γ_Path·J_Path + b2·k_SC·ψ_src − b3·θ_Coh
- S04: S_soft ≈ − c1·θ_Coh + c2·η_Damp − c3·zeta_topo; A_hys^E ≈ h(γ_Path, k_STG)
- S05: β_low/high ≈ 1 + d1·θ_Coh − d2·η_Damp + d3·k_STG·G_env, f_b ∝ ξ_RL^{-1}; J_Path = ∫_gamma (∇μ_rad · d ell)/J0
Mechanistic Highlights (Pxx)
- P01 · Path/Sea Coupling: γ_Path×J_Path with k_SC opens the drain channel, setting Λ_drop and τ_dep.
- P02 · STG/TBN: STG sets threshold loops/direction; TBN controls depletion floor and waiting-time tails.
- P03 · Coherence Window/Response Limit: clamp f_b and the maximal depletion depth.
- P04 · Topology/Reconstruction: zeta_topo tunes connectivity, impacting τ_rec and C_{P,E}.

VI. Concluding Assessment
Strengths
- Unified multiplicative structure (S01–S05): jointly captures τ_dep/Λ_drop/τ_rec with A_hys^E/C_{P,E}, S_soft/ΔHR, θ_wait/ζ_ava, and {β_low, β_high}/f_b, with interpretable parameters guiding band selection and trigger thresholds.
- Mechanism identifiability: posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL/ζ_topo disentangle path modulation, thresholding, noise floor, and network topology.
- Engineering utility: online G_env/ψ_env/J_Path monitoring plus geometric/interface shaping can tune attainable depletion depth and recovery time and enhance measurable covariances.
Limitations
- Extreme deep depletion: for Λ_drop ≥ 8 and τ_dep ≤ 30 ms, fractional-memory kernels and nonlinear shot statistics may be required.
- Geometric confounds: strong curvature/viewing effects may mimic energy draining; multi-band and angular cross-checks are needed.
Falsification Line & Experimental Suggestions
- Falsification line: see the Front-Matter falsification_line.
- Experiments:
- 2D maps: plot Energy stock × Time and E_peak × P to localize depletion–recovery hysteresis.
- Trigger optimization: increase sampling to resolve minimal τ_dep/τ_rec and stabilize f_b estimates.
- Polarimetry co-measurement: during strong depletion windows, measure P, χ to validate C_{P,E} and A_hys^E.
- Environmental suppression: reduce ψ_env (isolation/shielding/thermal control) to calibrate TBN impacts on {β_low, β_high} and θ_wait.
