Models of exponential and power-law acceleration of the Universe in Horndeski theory without ghosts and Laplace instabilities
Ruslan K. Muharlyamov, Tatiana N. Pankratyeva, Shehabaldeen O. A. Bashir
We present a designer method for flat Friedman-Robertson-Walker space-times within the framework of Horndeski's scalar-tensor theory. As a result, one can find subclasses of Hornde…
Exact cosmological solutions with magnetic field in the theory of gravity with non-minimal kinetic coupling
Ruslan K. Muharlyamov, Tatiana N. Pankratyeva, Shehabaldeen O. A. Bashir
We investigate anisotropic and homogeneous cosmological models in the scalar-tensor theory of gravity with non-minimal kinetic coupling of a scalar field to the curvature given by…
Magnetic Bianchi-I cosmology in the Horndeski theory
Ruslan K. Muharlyamov, Tatiana N. Pankratyeva, Shehabaldeen O. A. Bashir
We study the evolution of Bianchi-I space-times within the framework of the Horndeski theory with . The space-times are filled a global unidirectional electroma…
Reconstruction in the Horndeski theory within the scope of the Bianchi I cosmology
Ruslan K. Muharlyamov, Tatiana N. Pankratyeva
In the previous article Eur. Phys. J. Plus 136, 590 (2021) (arXiv: 2110.15396) we have proposed a reconstruction method for the kinetic gravity braiding theory in the framework of…
Reconstruction method in the kinetic gravity braiding theory with shift-symmetric
Ruslan K. Muharlyamov, Tatiana N. Pankratyeva
We present a reconstruction method for flat Friedman-Robertson-Walker (FRW) spacetime in a subclass of Horndeski theory -- specifically shiftsymmetric, the kinetic gravity braiding…
The nonlinear anisotropic model of the Universe with the linear potential
Ruslan K. Muharlyamov, Tatiana N. Pankratyeva
In the Bianchi I cosmology some subclasses of the Horndeski theory allow for the non-standard anisotropy behavior. For example, the anisotropy is damped near the initial singularit…
Anisotropic cosmological models in Horndeski gravity
Rafkat Galeev, Ruslan Muharlyamov, Alexei A. Starobinsky +2
It was found recently that the anisotropies in the homogeneous Bianchi I cosmology considered within the context of a specific Horndeski theory are damped near the initial singular…
Axion-induced oscillations of cooperative electric field in a cosmic magneto-active plasma
Alexander B. Balakin, Ruslan K. Muharlyamov, Alexei E. Zayats
We consider one cosmological application of an axionic extension of the Maxwell-Vlasov theory, which describes axionically induced oscillatory regime in the state of global magneti…
Electromagnetic waves in an axion-active relativistic plasma non-minimally coupled to gravity
Alexander B. Balakin, Ruslan K. Muharlyamov, Alexei E. Zayats
We consider cosmological applications of a new self-consistent system of equations, accounting for a nonminimal coupling of the gravitational, electromagnetic and pseudoscalar (axi…
Nonminimal Einstein-Maxwell-Vlasov-axion model
Alexander B. Balakin, Ruslan K. Muharlyamov, Alexei E. Zayats
We establish a new self-consistent system of equations accounting for a nonminimal coupling of the cooperative gravitational, electromagnetic and pseudoscalar (axion) fields in a m…
Non-minimal electrodynamics and resonance interactions in relativistic plasma
A. B. Balakin, R. K. Muharlyamov
A three-parameter toy-model, which describes a non-minimal coupling of gravity field with electromagnetic field of a relativistic two-component electrically neutral plasma, is disc…
Local spherically symmetric perturbations of spatially flat Friedmann models
A. A. Popov, R. K. Muharlyamov
The spherically symmetric perturbations in the spatially flat Friedman models are considered. It is assumed that the Friedmannian density and pressure are related through a linear…
