The Collapse of Duality: The Double-Slit Experiment as Tensor Interference and Geometric Decoherence in the DQ Framework

This paper offers a strictly deterministic and causal resolution to the iconic Double-Slit Experiment, eradicating the need for the mysticism inherent in the "observer effect" and classical wave-particle duality. Using the Quantum Diffusion (QD) framework, it is shown that the particle does not possess a dual nature, but is invariably a topological perturbation (tensor wave) of the 12-dimensional subspace 𝐹μν. The interference pattern arises from the flow of this perturbation through channels of high spatial diffusivity 𝐷. Furthermore, it is shown that the "wavefunction collapse" induced by a detector is not a product of conscious observation, but rather of the physical injection of gauge asymmetry and electromagnetic friction into the slits, which drastically alters the local diffusivity gradient, destroying the geometric coherence of the tensor wave and forcing a localized trajectory.
