The Quantum Electrodynamics in a Constant Magnetic Field—The Perturbation Theory in Furry Picture††This paper is one of the reports at The Second Conference on Particle Physics Theory in China held in Hangzhou from 28 Sept. to 4 Oct. 1982.

Abstract

The second quantization in furry picture is carried out, the perturbation theory is built up and a new method for investigating the electromagnetic phenomena in a constant magnetic field is proposed in this paper. Since the treatment of this method is exact, it is especially suitable for very high magnetic fields.
