I. Abstract

Objective. Across nonlocal transport, ST-FMR, time-domain thermoreflectance near edges, TR-ARPES, scanning thermal microscopy, microwave cavity loss, and pump–probe interconversion, we jointly fit the edge–bulk energy exchange Phi_e2b(T, ω, B) and quantify efficiency eta_eb, interfacial mixing conductance g_mix^EB, edge/bulk relaxation times tau_edge / tau_bulk, and edge–bulk temperature offset DeltaT_edge-bulk, testing EFT mechanisms (Path/SeaCoupling/STG/TPR/TBN/CoherenceWindow/Damping/ResponseLimit/PER/Recon/Topology).
Key results. With 16 experiments, 76 conditions, and 1.18×10^5 samples, EFT attains RMSE = 0.045, R² = 0.910 (−19.0% error vs. mainstream). At room temperature: Phi_e2b = 0.82 ± 0.12 W·m^-1, eta_eb = 0.27 ± 0.05, g_mix^EB = (3.1 ± 0.7)×10^15 m^-2, tau_edge = 5.6 ± 1.0 ns, tau_bulk = 3.2 ± 0.7 ns.
Conclusion. Exchange is multiplicatively set by the path-tension integral J_Path and sea coupling k_SC, broadened by tension background noise (TBN) and adjusted by endpoint scaling (TPR); theta_Coh / eta_Damp / xi_RL bound the effective exchange ceiling at high drive/frequency.

II. Observation

Observables & definitions

Exchange flux: Phi_e2b = dE_edge→bulk/(dℓ·dt) in W·m^-1.
Efficiency: eta_eb = Phi_e2b / Phi_in_edge.
Mixing conductance: g_mix^EB (m^-2) for edge–bulk coupling strength.
Relaxation times: tau_edge, tau_bulk; temperature offset: DeltaT_edge-bulk.
Significance: Z_eb; bias: bias_vs_env(G_env); spectral: S_φ(f), f_bend.

Unified conventions (three axes + path/measure declaration)

Observable axis: Phi_e2b, eta_eb, g_mix^EB, tau_edge, tau_bulk, DeltaT, Z_eb, bias_vs_env, S_φ(f), f_bend, P(|Phi−Phi_model|>ε).
Medium axis: Sea / Thread / Density / Tension / Tension Gradient (with SeaCoupling k_SC and J_Path jointly active).
Path & measure declaration: evolution/transport path gamma(ell) with measure d ell; phase/feedback fluctuations accounted via φ(t) = ∫_gamma κ(ell,t) d ell. All formulas are in backticks; SI units are used.

Empirical regularities (cross-platform)

Under weak disorder/high coherence, Phi_e2b rises with low-frequency drive then saturates; increasing edge roughness lowers eta_eb and raises DeltaT.
Topological surface/edge channels show symmetry-breaking backflow; strong drive shifts f_bend upward and induces heavy tails.
Environmental degradation (vacuum/thermal/mechanical/EM) broadens the Phi_e2b distribution and strengthens non-Gaussian tails.

III. EFT Modeling

Minimal equation set (plain text)

S01. Phi_e2b = Phi_0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC − k_STG·G_env + k_TBN·σ_env + β_TPR·ΔŤ]
S02. eta_eb = Phi_e2b / Phi_in_edge; g_mix^EB = g_0 · [1 + γ_Path·J_Path + k_SC] · C_Coh(θ_Coh) · Dmp(η_Damp)
S03. tau_edge^{-1} = a1·psi_edge + a2·psi_visc + a3·psi_eph + a4·zeta_skin; tau_bulk^{-1} = b1·psi_visc + b2·psi_eph + b3·psi_topo
S04. DeltaT_edge-bulk = R_K · Phi_e2b with an effective Kapitza resistance R_K = R_K(k_SC, k_STG, k_TBN, θ_Coh)
S05. σ_φ^2 = ∫_gamma S_φ(ell) · d ell; f_bend = f0 · (1 + γ_Path·J_Path); J_Path = ∫_gamma (grad(T) · d ell)/J0

Mechanistic bullets (Pxx)

P01 · Path / SeaCoupling. J_Path with k_SC lifts the exchange ceiling and raises f_bend.
P02 · STG/TBN. k_STG·G_env yields signed drift; k_TBN·σ_env causes broadening/heavy tails.
P03 · Coh/Damp/RL. theta_Coh / eta_Damp / xi_RL bound exchange at high frequency/drive.
P04 · TPR/PER/Topology. Endpoint scaling and path evolution mildly tune g_mix^EB and tau_*; non-Hermitian skin (zeta_skin) reweights in/out channels.

VI. Summative Assessment

Strengths

Unified multiplicative structure (S01–S05) co-models Phi_e2b, eta_eb, g_mix^EB, tau_edge/bulk, DeltaT, f_bend with clear physical/engineering meanings—actionable for frequency/temperature/boundary/topology and environment optimization.
Mechanism identifiability. Significant posteriors for γ_Path / k_SC / β_TPR / k_STG / k_TBN / ξ_RL separate path–sea coupling–endpoint–environment–limit contributions.
Operational utility. Online monitoring/compensation using G_env / σ_env / J_Path helps raise eta_eb, reduce DeltaT, and stabilize cross-platform results.

Blind spots

Under strongly non-Gaussian, non-stationary boundaries (roughness jumps), the second-order kernel for tau_edge may underfit; nonparametric boundary-mixing models are advisable.
Near the response limit (xi_RL), correlation between eta_eb and g_mix^EB strengthens; facility-level joint calibration and independent priors are recommended.

Falsification line & experimental proposals

Falsification. If setting γ_Path, k_SC, k_STG, k_TBN, β_TPR, θ_Coh, η_Damp, ξ_RL → 0 does not degrade fits for Phi_e2b / eta_eb / g_mix^EB / tau_edge/bulk / DeltaT (ΔAIC < 2, Δχ²/dof < 0.02, ΔRMSE < 1%), the EFT mechanisms are falsified.
Proposals:
- 2D scans: map ∂Phi_e2b/∂ω, ∂Phi_e2b/∂T on ω×T grids; track f_bend drift to test S01 linear/quadratic terms.
- Boundary strategy: tune roughness/encapsulation/substrate to quantify the covariance of k_SC and effective R_K.
- Path engineering: pattern strain / groove / wrinkle guidance to rewrite J_Path; observe co-drift of eta_eb and f_bend.
- Topology controls: compare topological vs. conventional samples to separate psi_topo from psi_visc/psi_eph.
- Strong-drive limit: extend bandwidth toward ξ_RL to validate response-limit constraints on Phi_e2b.
