Dynamic Aether as a Trigger for Spontaneous Spinorization in Early Universe

Universe, 2023
In the framework of the Einstein–Dirac-aether theory we consider a phenomenological model of the spontaneous growth of the fermion number, which is triggered by the dynamic aether.

Interaction of the axionic dark matter, dynamic aether, spinor and gravity fields as an origin of oscillations of the fermion effective mass

European Physical Journal C: Particles and Fields, 2021
In the framework of the Einstein–Dirac-axion-aether theory we consider the quartet of self-interacting cosmic fields, which includes the dynamic aether, presented by the unit timelike vector field, the axionic dark mater, described by the pseudoscalar ...

Nonlocal extension of causal thermodynamics of the isotropic cosmic fluid

Physics Letters B, 2022
We establish the nonlocal generalization of the Israel-Stewart model for the relativistic causal thermodynamics of the cosmic fluid, which evolves in the homogeneous isotropic Universe.

New application of the Killing vector field formalism: modified periodic potential and two-level profiles of the axionic dark matter distribution

European Physical Journal C: Particles and Fields, 2020
We consider the structure of halos of the axionic dark matter, which surround massive relativistic objects with static spherically symmetric gravitational field and monopole-type magneto-electric fields.

On the 2PN Pericentre Precession in the General Theory of Relativity and the Recently Discovered Fast-Orbiting S-Stars in Sgr A*

Universe, 2021
Recently, the secular pericentre precession was analytically computed to the second post-Newtonian (2PN) order by the present author with the Gauss equations in terms of the osculating Keplerian orbital elements in order to obtain closer contact with the

Is the Axionic Dark Matter an Equilibrium System?

Universe, 2020
We consider an axionic dark matter model with a modified periodic potential for the pseudoscalar field in the framework of the axionic extension of the Einstein-aether theory.

Spontaneous Color Polarization as A Modus Originis of the Dynamic Aether

Universe, 2020
We suggest the phenomenological model of emergence of the dynamic aether as a result of decay of the SU(N) symmetric field configuration containing the multiplet of vector fields.

Irreversibility of time in general relativity [PDF]

Известия Саратовского университета. Новая серия: Физика, 2022
Background and Objectives: The equations of classical dynamics of particles and waves admit solutions with the reverse flow of time. Therefore, it is generally assumed that classical dynamics does not reflect the irreversibility of time.

Conventionalism, Cosmology and Teleparallel Gravity

Universe, 2023
We consider homogeneous and isotropic cosmological models in the framework of three geometrical theories of gravitation. In Einstein’s general relativity, they are given in terms of the curvature of the Levi-Civita connection in torsion-free metric ...

Einstein–Maxwell-axion theory: dyon solution with regular electric field

European Physical Journal C: Particles and Fields, 2017
In the framework of the Einstein–Maxwell-axion theory we consider static spherically symmetric solutions which describe a magnetic monopole in the axionic environment.
