Dynamic Aether as a Trigger for Spontaneous Spinorization in Early Universe

open access: yesUniverse, 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.

GENERALIZED SPACES OF GENERAL RELATIVITY, II [PDF]

open access: greenProceedings of the National Academy of Sciences, 1960
1. This paper is a revision of the paper with the same title which was published a year ago. The paper deals with a space of four dimensions V4 of coordinates xi as i takes the values 1 to 4. The geometry of the space is based upon the asymmetric functions gij and the asymmetric coefficients of connection Prk and upon the Einsteinm equation2 gij,k ...

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

open access: yesEuropean 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.

Determinism and General Relativity [PDF]

open access: yesPhilosophy of Science, 2021
We investigate the fate of determinism in general relativity (GR), comparing the philosopher’s account with the physicist’s well-posed initial value formulations. The fate of determinism is interwoven with the question of what it is for a spacetime to be ‘physically reasonable’.

Is the Axionic Dark Matter an Equilibrium System?

open access: yesUniverse, 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

open access: yesUniverse, 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.

Towards Multifractality through an Ernst-Type Potential in Complex Systems Dynamics

open access: yesEntropy, 2023
Some possible correspondences between the Scale Relativity Theory and the Space–Time Theory can be established. Since both the multifractal Schrödinger equation from the Scale Relativity Theory and the General Relativity equations for a gravitational ...
