Electromagnetic field with induced massive term: Case with spinor field
Yu. P. Rybakov, G. N. Shikin, Yu. A. Popov +1
We consider an interacting system of spinor and electromagnetic field, explicitly depending on the electromagnetic potentials, i.e., interaction with broken gauge invariance. The L…
Scalar field in cosmology: Potential for isotropization and inflation
Yu. P. Rybakov, G. N. Shikin, Yu. A. Popov +1
The important role of scalar field in cosmology was noticed by a number of authors. Due to the fact that the scalar field possesses zero spin, it was basically considered in isotro…
Electromagnetic field with induced massive term: Case with scalar field
Yu. P. Rybakov, G. N. Shikin, Yu. A. Popov +1
We consider an interacting system of massless scalar and electromagnetic field, with the Lagrangian explicitly depending on the electromagnetic potentials, i.e., interaction with b…
Magneto-dilatonic Bianchi-I cosmology: isotropization and singularity problems
K. A. Bronnikov, E. N. Chudaeva, G. N. Shikin
We study the evolution of Bianchi-I space-times filled with a global unidirectional electromagnetic field interacting with a massless scalar dilatonic field according to t…
Self-gravitating stringlike configurations from nonlinear electodynamics
K. A. Bronnikov, G. N. Shikin, E. N. Sibileva
We consider static, cylindrically symmetric configurations in general relativity coupled to nonlinear electrodynamics (NED) with an arbitrary gauge-invariant Lagrangian of the form…
Spherically symmetric scalar vacuum: no-go theorems, black holes and solitons
K. A. Bronnikov, G. N. Shikin
We prove some theorems characterizing the global properties of static, spherically symmetric configurations of a self-gravitating real scalar field in general relativity (GR) in va…
