Efrain J. Ferrer, Vivian de la Incera
TL;DR
This paper demonstrates that a magnetic field can dynamically induce an anomalous magnetic moment in massless QED, leading to Zeeman splitting in higher Landau levels and providing new expressions for g-factor and Bohr magneton.
Contribution
It introduces a non-perturbative mechanism for magnetic moment induction in massless QED and derives related physical quantities, expanding understanding of magnetic effects in quantum electrodynamics.
Findings
Magnetic moment is dynamically induced in massless QED by an external magnetic field.
Zeeman splitting occurs in Landau levels above l=0 due to the induced magnetic moment.
Derived non-perturbative expressions for g-factor and Bohr magneton.
Abstract
It is shown that in non-perturbative massless QED an anomalous magnetic moment is dynamically induced by an applied magnetic field. The induced magnetic moment produces a Zeeman splitting for electrons in Landau levels higher than . The expressions for the non-perturbative Lande g-factor and Bohr magneton are obtained. Possible applications of this effect are outlined.
