We consider 6D manifolds with the structure M0 x M1 x M2, where M0 is 2D Lorentzian space-time while each of M1 and M2 can be a 2-sphere or a 2-torus.Among such geometries, we find examples of regular solutions of 6D general relativity with a scalar field as a source of gravity, which depend on a single coordinate x ranging over the whole real axis, with different asymptotic behavior at plus...

The main goal of the AEgIS collaboration is the measurement of the gravitational acceleration of antimatter in the Earth field. The AEgIS experiment is presently taking data at the CERN Antiproton Decelerator (AD) facility. The first step of the measurement is the creation of a beam of anti-hydrogen through the combination of antiprotons and positrons. The beam will be directed toward a moiré...

We study scalar field models with polynomial self-interaction. We write out conditions for the potential which are to be satisfied for kinks with power-law asymptotics to exist. Using the model $\varphi^8$ as an example, we show that power-law asymptotics of kinks lead to their long-range interaction. Within the collective coordinate approximation we estimate the effective kink-antikink...

A $(n+1)$-dimensional gravitational model with Gauss-Bonnet term and cosmological constant term is considered. When ansatz with diagonal cosmological metrics is adopted, the solutions with exponential dependence of scale factors: $a_i \sim \exp{ ( v^i t) }$, $i =1, \dots, n $, are considered.
We study the stability of the solutions with non-static volume factor, i.e. if
$K(v) = ...

The theory of the cosmological inflation successfully describes the accelerated expansion of the universe evolution at early stages. Also, inflation in the early universe has become the standard model for the generation of cosmological perturbations in the universe, the seeds for large-scale structure and temperature anisotropies of the cosmic microwave background. Quantum fluctuations of the...

In 1930, Reichenbach established the possibility of generalization of Einstein's definition of synchronizing spatially separated a couple of hours, introducing Reichenbach parameter that varies from zero to one, which defines one-way speed of light. A fundamental constant is the average speed of light back and forth. The independence of this observed value of the choice of inertial reference...

An extension of the Standard Model is considered, which is built on the basis of the Randall-Sundrum model with two branes. The metric of the background solution is not flat, which allows to solve the hierarchy problem of the gravitational interaction. In the case of unstabilized interbrane distance the model predicts the existence of the "strongly" coupled massless scalar mode, the radion,...
