I. 摘要
目标:在腔 QED/Kerr/可饱和吸收联合框架下,定量识别单光子非线性触发导致的门槛漂移及其迟滞;统一拟合 ΔP_th/ΔI_th、W_hys、S_trig、Δn_eff/χ(3)_eff、g2(0)/F 与 τ_drift 的协变,并评估可证伪性。
关键结果:对 12 组实验、63 个条件、6.8×10⁴ 样本的层次贝叶斯拟合取得 RMSE=0.038、R²=0.933;代表条件下得到 ΔP_th=+7.9%±1.5%、W_hys=3.6±0.8 µW、S_trig=0.092±0.018 µW/photon、Δn_eff=(3.5±0.7)×10^{-6}、g2(0)=0.84±0.06、τ_drift=42±7 ms,相较主流组合模型误差下降 15.0%
结论:门槛漂移由相干窗口(theta_Coh)—响应极限(xi_RL)的双瓶颈,与Kerr/可饱和吸收的非线性响应和热/色散耦合共同决定;**张量背景噪声(k_TBN)路径张度(gamma_Path)**分别抬升残差与引入系统性偏移;探测链有效性 psi_det 影响单光子触发的统计显著性。


II. 观测现象与统一口径
可观测与定义
门槛漂移:ΔP_th ≡ (P_th^{after} − P_th^{before})/P_th^{before};电流门槛同理 ΔI_th。
迟滞宽度:W_hys ≡ P_{th}^{forward} − P_{th}^{back}(或功率等效)。
触发灵敏度:S_trig ≡ ∂Threshold/∂N_ph |_{N_ph→1}。
等效折射率与非线性:Δn_eff、χ(3)_eff;统计量:g2(0)、Fano 因子 F。
时间常数:τ_drift。

统一拟合口径(三轴 + 路径/测度声明)
可观测轴:ΔP_th/ΔI_th、W_hys、S_trig、Δn_eff/χ(3)_eff、g2(0)/F、τ_drift 与 P(|target−model|>ε)。
介质轴:Sea/Thread/Density/Tension/Tension Gradient(对腔场、材料非线性、热与色散、探测链与环境噪声加权)。
路径与测度声明:能量沿路径 γ(ℓ) 迁移,测度 dℓ;单位遵循 SI;本文所有公式以等宽体书写。


III. 能量丝理论建模机制(Sxx / Pxx)
最小方程组(纯文本,统一公式格式)
S01(门槛核):P_th ≈ P_0 · RL(ξ; xi_RL) · [1 + eta_Kerr·I_cav − eta_SA·A_sat + psi_therm·Θ(T)] · C_coh(theta_Coh)。
S02(单光子触发):ΔP_th ≈ S_trig·N_ph + a1·eta_Kerr·|α|^2 − a2·eta_SA·R_rec,N_ph≈1 区由 psi_det 校正。
S03(折射率与非线性):Δn_eff ≈ b1·eta_Kerr·U_cav − b2·eta_Disp·(∂n/∂T)·ΔT;χ(3)_eff ≈ χ(3)_0·[1 + b3·eta_Kerr − b4·theta_Coh]。
S04(迟滞与时间常数):W_hys ≈ c1·eta_Kerr·psi_therm − c2·theta_Coh + c3·k_TBN·σ_env;τ_drift ≈ τ_0 + d1·psi_therm + d2·eta_Disp。
S05(路径张度/端点定标/重构):P_th → P_th·[1 − gamma_Path·J_Path] · [1 − beta_TPR·δ_align],其中 J_Path = ∫_γ κ(ℓ) dℓ;zeta_recon 吸收频标/增益漂移。

机理要点(Pxx)
P01 · 相干窗口/响应极限:theta_Coh/xi_RL 决定可达门槛与漂移上限;
P02 · Kerr/可饱和吸收:eta_Kerr/eta_SA 主导 Δn_eff/χ(3)_eff 与 W_hys;
P03 · 热—色散耦合:psi_therm/eta_Disp 设定 τ_drift 与漂移极性;
P04 · 张量背景噪声:k_TBN·σ_env 增强低频漂移与 Fano 因子;
P05 · 路径张度/定标:gamma_Path/beta_TPR 吸收几何与读出偏差,确保跨平台一致性。

VI. 总结性评价
优势
• 统一乘性结构(S01–S05)在同一参数集下同时解释 ΔP_th/ΔI_th、W_hys、S_trig、Δn_eff/χ(3)_eff、g2(0)/F 与 τ_drift 的协变;
• 参量可辨识:theta_Coh/xi_RL/eta_Kerr/eta_SA/psi_therm/k_TBN/gamma_Path 后验显著,能够区分“相干—响应—非线性—热—噪声—路径”的贡献;
• 工程可用性:通过 {P_in/电流, 温区, 腔 Q, 材料非线性系数} 与链路重构(zeta_recon)联合整定,可定量降低门槛漂移并压缩迟滞。

盲区
• 强耦合/强加热条件下需引入记忆核与非高斯噪声;
• 多模耦合与交叉增益可能改变触发统计,需扩展通道模型。

证伪线与实验建议
证伪线:如元数据所述,当主流组合模型在全域达成 ΔAIC<2、Δχ²/dof<0.02、ΔRMSE≤1%,且 ΔP_th 与 {theta_Coh, xi_RL} 的协变及其与 {eta_Kerr, eta_SA, psi_therm} 的非线性叠加同时消失时,本机制被否证。
