Abstract:
The description of gravitation in the framework of soliton interaction is considered for two nonlinear field models. These models are Born — Infeld nonlinear electrodynamics and so-called Born — Infeld type scalar field model. The last model can also be called the extremal space-time film one because of the specific form of the appropriate variational principle. Gravitational interaction is considered in the context of unification for all interactions of material particles. It is shown that long-range interaction of solitons of the models appears as force one and metrical one. The force intera

Abstract:
The Weyl curvature includes the Newtonian field and an additional field, the so-called anti-Newtonian. In this paper, we use the Bianchi and Ricci identities to provide a set of constraints and propagations for the Weyl fields. The temporal evolutions of propagations manifest explicit solutions of gravitational waves. We see that models with purely Newtonian field are inconsistent with relativistic models and obstruct sounding solutions. Therefore, both fields are necessary for the nonlocal nature and radiative solutions of gravitation.

Abstract:
We construct a model for considering the quantum correction of the gravitational constant. In the model, the gravitational constant originates from a coupling between the gravitational field and a scalar field. If the scalar field, as it should be in the real physical world, is a quantum field, the gravitational constant will have a quantum correction. The quantum correction, generally speaking, varies with spacetime coordinates. Therefore, the gravitational constant is no longer a constant. In different spacetime, the quantum correction is different, for the coupling in different spacetime is

Despite the many successes of the current standard model of cosmology on the largest physical scales, it relies on two phenomenologically motivated constituents, cold dark matter and dark energy, which account for approximately 95% of the energy-matter content of the universe. From a more fundamental point of view, however, the introduction of a dark energy (DE) component is theoretically challenging and extremely fine-tuned, despite the many proposals for its dynamics. On the other hand, the concept of cold dark matter (CDM) also suffers from several issues such as the lack of direct experime

The theories of gravity are one of the most important topics in theoretical physics and mathematical physics nowadays. The classical formulation of gravity uses the Hilbert-Einstein Lagrangian, which is a singular second-order Lagrangian; hence it requires a geometric theory for second-order field theories which leads to several difficulties. Another standard formulation is the Einstein-Palatini or Metric-Affine, which uses a singular first order Lagrangian. Much work has been done with the aim of establishing the suitable geometrical structures for describing classical field theories. In

We show that r-modes can generate very strong toroidal fields in the core of accreting millisecond pulsars by inducing differential rotation.

Immediately after, however, this elegant S-matrix theory of the strong interactions lost its phenomenological battle against a more, but not quite, conventional quantum field theory risking, around 1974, total oblivion.

The model consists of a generator of the low-frequency noise modeled the signal of the stochastic GW background and a block of pulsar timing array data processing. The data processing is carried out with the help of statistical methods based on the frequentist interpretation of probability. The model under discussion is used for processing one of the generated GW background realizations. The result of the data processing is the estimates of the likelih

Abstract:
Using an eigenvector and signal component analyzer (eigenoscope), the problem of identifying the impact of gravitational waves of relativistic binary star systems (RBSS) with large and small eccentricity on the vertical component of the electric field strength ($E_\text{z}$) in the Earth's atmospheric surface layer in the infra-low frequency (ILF) range at high harmonics of the EDS circulation frequencies has been solved. The results were obtained using monitoring data at four spatially separated $E_\text{z}$ observation stations. A model is proposed to explain the effect of the gravitational

Abstract:
We study the quantum-mechanical problem of a spin 1/2 particle in gravitational field of the black hole with Newman-Unti-Tamburino (NUT) parameter. Separation of the variables has been performed in the Dirac equation. The system of angular equations has been solved analytically in terms of hypergeometric functions. The quantization condition for the angular parameter is derived. In the massless case, the radial system is reduced to separate systems of two first-order equations which are solved in terms of the confluent Heun functions. Generalized tortoise-like coordinate is introduced, and exp
