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.

Motion of Charged Spinning Particles in a Unified Field

Advances in High Energy Physics, 2021
Using a geometry wider than Riemannian one, the parameterized absolute parallelism (PAP) geometry, we derived a new curve containing two parameters. In the context of the geometrization philosophy, this new curve can be used as a trajectory of charged ...

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.

A unifying physically meaningful relativistic action

Scientific Reports, 2022
The motion of an object under the influence of force fields and/or media is described by means of a world-line with least action in its influenced spacetime.

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.

Relative thermalization [PDF]

Physical Review E, 2016
When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that a more general and relevant question is "when does a system thermalize relative to a particular reference?" By relative thermalization we mean that, as well as being in a ...

Relativity without relativity [PDF]

Classical and Quantum Gravity, 2002
We give a derivation of general relativity and the gauge principle that is novel in presupposing neither spacetime nor the relativity principle. We consider a class of actions defined on superspace with two key properties. The first is 3-coordinate invariance. This is the only postulated symmetry, and it leads to the standard momentum constraint.

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.
