Exact formulations of relativistic electrodynamics and magnetohydrodynamics with helically coupled scalar field
arXiv:2211.03926 · doi:10.1103/PhysRevD.107.083020
Abstract
We present the general relativistic electrodynamics and magnetohydrodynamics with a helically coupled scalar field. We consider three component system with the fluid, scalar field and electromagnetic fields with the helical coupling. We derive three exact formulations: the covariant formulation, the ADM formulation, and the fully nonlinear and exact perturbation formulation. We also derive the weak-gravity limit with fully relativistic fluid and fields. The latter two formulations are presented in the cosmological context.
