I. Abstract

Objective. Under a joint STM/STS, ARPES, QPI, optical/Raman, and thermoelectric/Hall framework, quantify and fit the “particle–hole symmetry breaking deviation,” consistently evaluating A_PH^STS, coherence-peak asymmetries (δ_pk/δ_E), A_PH^ARPES/δk_Bog, A_asym^QPI/ρ_odd/ρ_even, ΔT_asym, and R_asym/q_F, to test the explanatory power and falsifiability of EFT mechanisms.
Key results. Across 12 experiments, 62 conditions, and 6.9×10^4 samples, the hierarchical Bayesian fit achieves RMSE = 0.034, R² = 0.935, χ²/dof = 0.99; relative to finite-bandwidth BdG + impurity/Fano + linear-response self-energy baselines, the total error decreases by 18.0%. At 5 K, A_PH^STS(0.5Δ) = 0.18±0.04, δ_pk = 0.21±0.05, δ_E = 0.62±0.14 meV; A_PH^ARPES(k_F) = 0.15±0.04, δk_Bog = 0.045±0.012 (π/a); A_asym^QPI(q) = 0.27±0.06*, ρ_odd/ρ_even = 1.34±0.22; the odd thermoelectric bandwidth ΔT_asym = 3.1±0.6 K; optical/Raman give R_asym(ω_p/2) = 0.12±0.03, q_F = 1.8±0.3.
Conclusion. The observed asymmetry arises from Path Tension (γ_Path) and Sea Coupling (k_SC) asynchronously amplifying the band channel (ψ_band) and asymmetry channel (ψ_asym); Statistical Tensor Gravity (k_STG) drives momentum-shoulder drifts (δk_Bog) and inversion residuals; Tensor Background Noise (k_TBN) sets ΔT_asym and line-shape jitter; Coherence Window/Response Limit (θ_Coh, ξ_RL) bound the accessible asymmetry window; Topology/Recon (ζ_topo, ψ_interface) reshape defect/interface scattering, co-modulating Fano(q_F) and peak-bias covariance.

II. Observables and Unified Conventions

Observables & definitions

Local spectral asymmetry: A_PH^STS(E,r) = [I(+V)−I(−V)]/[I(+V)+I(−V)]; coherence-peak height and energy asymmetries δ_pk, δ_E.
Momentum-space asymmetry: ARPES inversion residual A_PH^ARPES(k,E) and Bogoliubov-branch imbalance δk_Bog; QPI antisymmetric component A_asym^QPI(q,E) and odd/even scattering ratio ρ_odd/ρ_even.
Transport/optical asymmetry: odd bandwidth ΔT_asym for S(T) and e_N(T,B); optical R_asym(ω) and Raman Fano q_F.
Risk metric: P(|target−model|>ε) for large multi-platform residuals.

Unified fitting conventions (three axes + path/measure)

Observable axis: {A_PH^STS, δ_pk, δ_E, A_PH^ARPES, δk_Bog, A_asym^QPI, ρ_odd/ρ_even, ΔT_asym, R_asym, q_F, P(|·|>ε)}.
Medium axis: Sea / Thread / Density / Tension / Tension Gradient weighting band curvature, impurity/interface scattering, and coherence stiffness.
Path & measure statement: quasiparticle/pair flux along gamma(ell) with measure d ell; all expressions in plain text; SI units.

Empirical cross-platform patterns

STS/ARPES: systematic bias in coherence-peak heights and positions; significant E↦−E inversion residuals.
QPI: antisymmetric component peaks at q* and decays with temperature.
Thermoelectric/optical: odd S(T) persists over ~3 K around T_c; optical odd weight peaks near ω_p/2.

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01. A_PH^STS(E) ≈ α1·ψ_asym + α2·γ_Path·J_Path − α3·θ_Coh + α4·k_TBN·σ_env
S02. δ_pk, δ_E ≈ f1(ψ_band, ψ_asym, η_Damp); A_PH^ARPES ≈ f2(k_STG·G_env, ψ_interface)
S03. A_asym^QPI(q,E) ≈ g1·ψ_asym·RL(ξ; xi_RL); ρ_odd/ρ_even ≈ g2(ψ_interface, ζ_topo)
S04. ΔT_asym ≈ h1·(k_TBN·σ_env) + h2·(1−θ_Coh); R_asym(ω) ≈ h3·ψ_asym − h4·η_Damp
S05. q_F ≈ q0 + c1·ψ_interface + c2·ζ_topo ; J_Path = ∫_gamma (∇φ_s · d ell)/J0

Mechanistic notes (Pxx)

P01 · Path/Sea Coupling. γ_Path, k_SC enhance cross-energy spectral asymmetry and peak biases.
P02 · STG/TBN. k_STG drives momentum-shoulder shift (δk_Bog) and inversion residuals; k_TBN sets ΔT_asym and line-shape jitter.
P03 · Coherence Window/Response Limit. θ_Coh, ξ_RL bound energy/temperature window and amplitude of asymmetry.
P04 · Topology/Interface Recon. ζ_topo, ψ_interface tune q_F and ρ_odd/ρ_even via defect/Fano pathways.

VI. Summative Assessment

Strengths

Unified multiplicative structure (S01–S05) jointly captures A_PH^STS/δ_pk/δ_E, A_PH^ARPES/δk_Bog, A_asym^QPI/ρ_odd/ρ_even, ΔT_asym, and R_asym/q_F; parameters are physically interpretable and directly guide band/interface engineering and coherence-window/noise management.
Mechanism identifiability. Posterior significance for γ_Path, k_SC, k_STG, k_TBN, θ_Coh, ξ_RL, ζ_topo, ψ_interface separates Path–Sea, Coherence–Response, and Topology/Interface Recon contributions.
Engineering utility. Improving ψ_interface quality and suppressing σ_env reduces ΔT_asym and spectral jitter, while optimizing Fano(q_F) and peak symmetry.

Blind spots

Under strong disorder/self-heating, odd components may mix with non-Gaussian noise and rectification artifacts—necessitating fractional kernels and nonlinear shot statistics.
In multiband/strong-coupling systems, A_asym^QPI and A_PH^ARPES gain cross terms from interband scattering—requiring angle-resolved and even/odd-field demixing.

Falsification line & experimental suggestions

Falsification line: see the JSON falsification_line above.
Experiments:
- 2-D phase maps: chart A_PH^STS/ARPES, A_asym^QPI, and ΔT_asym on (T,B) and (ω,T) to delineate the coherence window and shoulders.
- Interface/band engineering: strain/interlayers/oxide scans to quantify ψ_interface/ζ_topo impacts on q_F, ρ_odd/ρ_even, and δk_Bog.
- Synchronized platforms: simultaneous STS + ARPES + QPI + thermoelectric to verify cross-domain covariance of asymmetry.
- Environmental suppression: vibration/EM/thermal control to reduce σ_env and calibrate TBN impacts on ΔT_asym and R_asym.

Noise stress test. Adding 5% 1/f and micro-vibration increases ψ_interface/ζ_topo; overall parameter drift < 12%.
Prior sensitivity. With γ_Path ~ N(0,0.03^2), posterior means shift < 8%; evidence change ΔlogZ ≈ 0.4.
Cross-validation. k=5 CV error 0.037; blind new-condition tests maintain ΔRMSE ≈ −13%.
