Electron-Ion Coulomb Shearing as a Dominant Growth Mechanism in Eddington-Limited Regimes

This work presents a physical model for electron-ion separation in the inner environments of accreting black holes and its consequences for relativistic jet structure and black hole growth. The framework examines how differential forcing between electrons and ions can arise under extreme radiative, magnetic, and relativistic conditions, leading to species-dependent transport without invoking exotic physics or violations of known conservation laws. The model is developed with explicit attention to force balance, coupling timescales, plasma conditions, and observational constraints. It predicts stratified jet compositions, characteristic polarization and Faraday rotation signatures, and a modified effective inflow geometry that can permit sustained ion-dominated accretion under conditions where standard assumptions of tight electron-ion coupling break down. Worked examples and evaluation protocols are provided to enable direct comparison with observational data, including resolved jet systems and compact accreting sources. The paper is intended as a self-contained theoretical and phenomenological study, suitable for independent verification and future numerical or observational testing.
