DFIM Companion Note 1: Entanglement Formation as Weld Resonance—Validation from Attosecond Measurements (Version 1.1)

This companion note extends the Dual-Field Interface Model (DFIM) by interpreting quantum entanglement not as an instantaneous phenomenon, but as a dynamic "meeting" of positive and negative fields within the spacetime membrane weld. We analyze recent experimental data from TU Wien (Jiang et al., 2024), which measured the birth of entanglement in helium photoionization taking approximately 232 attoseconds. We show that this finite delay aligns with DFIM's prediction of non-instantaneous wave feedback across the interface. Key insights: Demystifying Non-Locality: We propose that "instantaneous" entanglement is merely an approximation for extremely fast weld resonance (τ≈10−16 s at atomic scales). Metric Dilation Effects: We demonstrate that while high-density regimes (like Black Holes) increase weld stiffness, relativistic time dilation (ceff=eψ) stretches the observable formation time, preserving causality and unitarity. Corroborative Evidence: This note provides empirical support for the non-adiabatic Landau-Zener mechanics proposed in DFIM v3.3 without requiring modifications to the core equations.
