# Duality Symmetry of Quantum Electrodynamics

@inproceedings{Yang2021DualitySO, title={Duality Symmetry of Quantum Electrodynamics}, author={Li-Ping Yang and Dazhi Xu}, year={2021} }

The duality symmetry between electricity and magnetism hidden in classical Maxwell equations suggests the existence of dual charges, which have usually been interpreted as magnetic charges and have not been observed in experiments. In quantum electrodynamics (QED), both the electric and magnetic fields have been unified into one gauge field Aμ, which makes this symmetry inconspicuous. Here, we recheck the duality symmetry of QED by introducing a dual gauge field. Within the framework of gauge…

The dual symmetry between electric and magnetic fields is an important intrinsic property of Maxwell equations in free space. This symmetry underlies the conservation of optical helicity and, as we…

The Theory of magnetic poles

If one supposes that a particle with a single magnetic pole can exist and that it interacts with charged particles, the laws of quantum mechanics lead to the requirement that the electric charges…

Electric–magnetic symmetry and Noether's theorem

- Physics

In the absence of charges, Maxwell's equations are highly symmetrical. In particular, they place the electric and magnetic fields on equal footing. In light of this electric–magnetic symmetry, we…

Magnetic Charge and Quantum Field Theory

A quantum field theory of magnetic and electric charge is constructed. It is verified to be relativistically invariant in consequence of the charge quantization condition…

Duplex symmetry and its relation to the conservation of optical helicity

In this paper, we discuss some interesting properties of the electromagnetic potentials in the quantum domain. We shall show that, contrary to the conclusions of classical mechanics, there exist…

Dual symmetric Lagrangians and conservation laws
