Curvature-Driven Reconstruction: A Local GR/QFT Mechanism Study

This paper develops a localized GR/QFT mechanism in which sufficiently compact high-density regions may depart from monotonic compression through curvature-induced radiative confinement, enhanced photon-photon interactions, and pair-production feedback. A phenomenological high-density correction to the Tolman-Oppenheimer-Volkoff equation is introduced as an effective representation of confinement-driven back-reaction, without modifying general relativity or invoking any global large-scale behavior. The mechanism is formulated through operational thresholds defined by timescale competition between radiative escape and dynamical compression, together with the onset of Breit-Wheeler pair production at high photon densities. The analysis is strictly local, exploratory, and mathematically explicit, and outlines conditions under which curvature-driven feedback may permit a localized departure from monotonic compression and possible re-expansion under extreme conditions.
