Dynamic nature of the anomalous magnetic moment of an electron in a constant magnetic field in topologically massive two-dimensional electrodynamics

Physical Review D - Particles, Fields, Gravitation and Cosmology. 2019. Vol. 100. No. 11. P. 115046-1-115046-12.

An analytical expression is obtained for the anomalous magnetic moment of an electron in a constant
magnetic field in topologically massive two-dimensional electrodynamics. In the limiting case of a
relatively weak magnetic field, asymptotic formulas are found, which specify the dependence of the
anomalous magnetic moment on the Chern-Simons parameter and dynamic parameter of synchrotron
radiation. The conditions are identified for the applicability of the computations of the anomalous magnetic
moment of an electron, which have previously been made based on the calculation of the vertex function in
two-dimensional electrodynamics with the Chern-Simons term.
