Generation of Primordial Magnetic Fields from the SV0 Quantum Bounce and Chiral Anomaly

Abstract: :The origin of the large-scale magnetic fields observed in galaxies and galaxy clusters remains one of the unsolved problems in cosmology. Standard mechanisms (such as the Biermann battery or inflationary fluctuations) struggle to produce seed fields of sufficient strength to explain these observations. In this paper (Paper LIII of the SV0 series), we propose a novel mechanism for the generation of Primordial Magnetic Fields within the Signed-Volume (SV0) framework. We show that during the quantum bounce, the intense exchange between the two sectors (V_A and V_B) generates a large chiral chemical potential. Through the Chiral Magnetic Effect (CME), this chemical potential induces a macroscopic electric current parallel to the magnetic field, leading to the rapid amplification of seed fields. We calculate the resulting magnetic field strength and find B ~ 10⁻⁹ G at the end of the bounce, which is precisely the required seed field for galactic dynamos. This provides a natural, first-principles origin for cosmic magnetism without requiring ad-hoc astrophysical processes. Keywords:Primordial Magnetic Fields; Chiral Magnetic Effect; Chiral Anomaly; SV0 Theory; Quantum Bounce; Early Universe; Cosmology.
