Particle-antiparticle asymmetry from magnetogenesis through the Landau mechanism

TL;DR

This paper proposes that early universe magnetic fields could explain particle-antiparticle asymmetry through a Lorentz and CPT violating extension of the Landau problem in quantum field theory, linking magnetogenesis to matter-antimatter imbalance.

Contribution

It introduces a novel quantum field theoretical extension of the Landau problem motivated by string theory, connecting early magnetic fields to matter-antimatter asymmetry.

Findings

Lorentz and CPT violation in field momenta commutators

Magnetic fields in early universe imply particle-antiparticle asymmetry

Proposes magnetogenesis as a mechanism for matter-antimatter imbalance

Abstract

Motivated by string theory an extension of the Landau problem to quantum field theory is considered. We show that the commutator between momenta of the fields violates Lorentz and CPT invariance leading to an alternative method of understanding the question of particle-antiparticle asymmetry. The presence of magnetic field at very early moments of the universe would then suggest that the particle-antiparticle asymmetry can be understood as a consequence of magnetogenesis.
