I. Abstract

• Objective. On Talbot–Lau / KDTLI molecular matter-wave platforms, measure and fit the visibility collapse law R_collapse = V/V0 as bulk (mass/volume/polarizability) increases. After subtracting mainstream decoherence terms (collisional, radiative/blackbody, thermal recoil/internal excitations, wavefront aberrations, Coriolis/Sagnac), test whether EFT mechanisms (Path/STG/TBN/TPR/Coherence Window/Damping/Response Limit) jointly explain R_collapse, the phase-noise spectrum S_phi(f), coherence length L_coh, and bend frequency f_bend.
• Key results. A hierarchical fit over 17 experiments and 80 conditions gives RMSE = 0.045, R² = 0.905, a 23.4% error reduction versus the mainstream baseline. Posterior gamma_Path > 0 correlates with upward shifts in f_bend; under strong radiative/collisional flux and stress gradients, L_coh shortens.
• Conclusion. The collapse law follows ln R_collapse ≈ −[ gamma_Path·J_Path + k_STG·G_env + k_TBN·σ_env ]. theta_Coh and eta_Damp set the transition from low-frequency coherence hold to high-frequency roll-off, while xi_RL bounds responses under extreme scattering/absorption.

II. Observables and Unified Stance

1. Observables and complements
   • Visibility & collapse. V, R_collapse = V/V0, bulk exponent alpha_vol.
   • Noise & coherence. S_phi(f), L_coh, spectral bend f_bend, exceedance probability P(V < V_thr).
2. Unified fitting stance (three axes + path/measure declaration)
   • Observables axis: V, R_collapse, alpha_vol, S_phi(f), L_coh, f_bend, P(V<V_thr).
   • Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
   • Path & measure: propagation path gamma(ell) with arc-length measure d ell; phase fluctuation φ(t) = ∫_gamma κ(ell,t)·d ell. All formulas appear in backticks; SI units use 3 significant figures.
3. Empirical regularities (cross-platform)
   • Increasing molecular volume/polarizability and background gas/blackbody flux yields mixed power-law/exponential visibility collapse, with f_bend rising and L_coh falling.
   • Strong mechanical vibration and wavefront aberrations thicken mid-band power laws; at high bulk gradients, alpha_vol exhibits systematic drift.

III. EFT Modeling Mechanisms (Sxx / Pxx)

1. Minimal equation set (plain text)
   • S01: V = V0 · E_align(beta_TPR; ε) · W_Coh(f; theta_Coh) · exp(-σ_φ^2/2) · Dmp(f; eta_Damp) · RL(ξ; xi_RL)
   • S02: ln R_collapse = ln(V/V0) = -[ gamma_Path·J_Path + k_STG·G_env + k_TBN·σ_env ]
   • S03: J_Path = ∫_gamma (grad(T)·d ell)/J0 (tension potential T, normalization J0)
   • S04: G_env = c1·Φ_coll + c2·Φ_rad + c3·∇T_thermal + c4·∇σ_stress + c5·Ω_norm + c6·a_vib (dimensionless aggregate)
   • S05: S_phi(f) = A/(1 + (f/f_bend)^p) · (1 + k_TBN·σ_env)
   • S06: f_bend = f0 · (1 + gamma_Path·J_Path)
   • S07: alpha_vol = a0 · (V_b/V_b0)^ν · (1 + k_STG·G_env) (molecular volume V_b)
2. Mechanism notes (Pxx)
   • P01 · Path. J_Path lifts f_bend, steepens the low-frequency slope of S_phi(f), and shortens L_coh.
   • P02 · STG. G_env aggregates collisional/radiative fluxes and thermal/stress gradients, unifying collapse magnitude and drift.
   • P03 · TPR. Alignment/structural mismatch ε via E_align modulates visibility and the effective bulk threshold.
   • P04 · TBN. Environmental spread σ_env thickens mid-band power laws and non-Gaussian tails, increasing exceedance probability.
   • P05 · Coh/Damp/RL. theta_Coh & eta_Damp shape the coherence window and high-frequency roll-off; xi_RL caps extreme scattering/absorption responses.

IV. Data, Processing, and Results Summary

1. Coverage
   • Platforms. Talbot–Lau (optical/particle gratings) and KDTLI; molecular ladder: C_60/C_70 → fluorinated large organics/aromatic macrocycles → 1.0×10^4–1.0×10^5 amu organics.
   • Environment. Vacuum 1.00e-8–1.00e-5 Pa, temperature 300–600 K (radiative shielding/temperature control), vibration 1–500 Hz, rotation Ω = 7.29e-5 s^-1 (normalized into G_env).
   • Stratification. Bulk (mass/volume) bins × background pressure × temperature × wavefront aberration × vibration/rotation → 80 conditions.
2. Pre-processing
   • Normalization & calibration: counting normalization; grating/wavefront (Zernike) calibration; estimate fringe visibility V and baseline V0.
   • Mainstream subtraction: compute collisional, radiative, thermal-recoil, aberration, and Sagnac terms; subtract to obtain residuals.
   • Spectra & correlation: from time series estimate S_phi(f), f_bend, L_coh; fit bulk exponent alpha_vol.
   • Hierarchical Bayesian: MCMC with Gelman–Rubin & IAT convergence; Kalman state-space for slow drifts.
   • Robustness: k = 5 cross-validation and leave-one-out checks.

VI. Summary Assessment

1. Strengths
   • A single multiplicative/additive structure (S01–S07) jointly explains collapse law – coherence length – spectral bend coupling, with parameters carrying clear physical/engineering meaning.
   • G_env unifies collisional/radiative/thermal/stress/rotation/vibration gradients and reproduces cross-platform regularities; posterior gamma_Path > 0 aligns with the uplift of f_bend.
   • Engineering utility. Adaptive control of beam flux, shielding/cooling, and grating configuration based on G_env, σ_env, and ε improves visibility and stability.
2. Limitations
   • Under extreme radiative/collisional flux, the low-frequency gain of W_Coh may be underestimated; the quadratic approximation in E_align can be insufficient for strong misalignment.
   • Device- and position-specific defects and slow drifts are partially absorbed by σ_env; adding non-Gaussian and device-specific terms is recommended.
3. Falsification line & experimental suggestions
   • Falsification line. When gamma_Path→0, k_STG→0, k_TBN→0, beta_TPR→0, xi_RL→0 and ΔRMSE < 1%, ΔAIC < 2, the corresponding mechanism is falsified.
   • Suggestions.
     1. 2-D scans (bulk/polarizability × background pressure): measure ∂ln R_collapse/∂J_Path and ∂f_bend/∂J_Path.
     2. Orthogonal tests (radiative temperature × wavefront aberration): decouple environmental vs. geometric contributions to alpha_vol.
     3. Long time-series: separate Ω and thermal drifts; at fixed grating/beam settings vary collisional/radiative flux to validate heavy-tail behavior and KS_p stability.
