The Negentropic Nuclear Sink: Modeling Baryonic Matter as a Dissipative Topological Defect of the Pre-Big Bang Vacuum

This paper introduces a novel framework that models the atomic nucleus as a localizedtopological defect in the cosmological arrow of time, characterized by a non-equilibriumthermodynamic inversion (∆Smicro < 0). Rather than treating baryonic matter as an in-trinsic gauge field source, we propose that the core of the atom is a residual pocket of spacethat preserves the ideal, low-entropy, cryogenic phase state of the Pre-Big Bang universe.We demonstrate that the boundary layer dynamics of the sub-nuclear radius eliminate theneed for active informational sorting mechanisms (Maxwell’s Demon) by utilizing a first-order topological phase transition. At sub-nuclear ranges (r < r0 ), the absolute drainageof the vacuum between nucleons triggers a dominant external hydrostatic pressure from thesurrounding high-density void, naturally replicating the strong nuclear force and asymptoticfreedom. Finally, we anchor this model in empirical data by demonstrating that this ther-modynamic inversion offers a robust, physical explanation for the anomalous negative heatcapacity recorded in heavy-ion multi-fragmentation calorimetry.
