Classical solutions in a Lorentz-violating Maxwell-Chern-Simons electrodynamics

Abstract

We take as a starting point the planar model arising from the dimensional reduction of Maxwell electrodynamics with the (Lorentz-violating) Carroll-Field-Jackiw term. We then write and study the extended Maxwell equations and the corresponding wave equations for the potentials. The solution to these equations shows some interesting deviations from the usual MCS electrodynamics, with background-dependent correction terms. In the case of a timelike background, the correction terms dominate over the MCS sector in the region far from the origin, and establish the behavior of a massless electrodynamics (in the electric sector). In the spacelike case, the solutions indicate the clear manifestation of spatial anisotropy, which is consistent with the existence of a privileged direction in space.
