Primordial Black Holes from Spatially Varying Cosmological Constant Induced by Field Fluctuations in Extra Dimensions
Arkady A. Popov, Sergey G. Rubin, Alexander S. Sakharov
The origin and evolution of supermassive black holes (SMBHs) in our universe have sparked controversy. In this study, we explore the hypothesis that some of these black holes may h…
Cosmology and matter induced branes
S. G. Rubin
The extra space paradigm plays a significant role in modern physics and in cosmology as the specific case. In this review, the relation between the main cosmological parameters - P…
Inhomogeneous compact extra dimensions
K. A. Bronnikov, R. I. Budaev, A. V. Grobov +2
We show that an inhomogeneous compact extra space possesses two necessary features --- their existence does not contradict the observable value of the cosmological constant i…
Classical transitions with the topological number changing in the early Universe
Vakhid A. Gani, Alexander A. Kirillov, Sergey G. Rubin
We consider classical dynamics of two real scalar fields within a model with the potential having a saddle point. The solitons of such model are field configurations that have the…
Reionization effect enhancement due to primordial black holes
K. M. Belotsky, A. A. Kirillov, N. O. Nazarova +1
Primordial black holes (PBH) could account for variety of phenomena like dark matter, reionization of the Universe, early quasars, coalescence of black holes registered through gra…
Signatures of primordial black hole dark matter
K. M. Belotsky, A. D. Dmitriev, E. A. Esipova +6
The nonbaryonic dark matter of the Universe is assumed to consist of new stable forms of matter. Their stability reflects symmetry of micro world and mechanisms of its symmetry bre…
Higgs-Like Field and Extra Dimensions
A. V. Grobov, S. G. Rubin
We study the origin of the Higgs field in the framework of the universal extra dimensions. It is shown that a Higgs-like Lagrangian can be extracted from a metric of an extra space…
Baryon number of the Universe as a result of extra space dynamics
A. V. Grobov, S. G. Rubin
Origin of baryon asymmetry is studied in the framework of extra dimensional approach. Baryon excess production and the symmetrization of extra-space are performed simultaneously. B…
Clusters of Black Holes as Point-Like Gamma-ray Sources
K. M. Belotsky, A. V. Berkov, A. A. Kirillov +1
The possibility of identifying some of Galactic gamma-ray sources as clusters of primordial black holes is discussed. The known scenarios of supermassive black hole formation indic…
Emergence of symmetries
A. A. Kirillov, A. A. Korotkevich, S. G. Rubin
The mechanism of symmetry formation is discussed in the framework of multidimensional gravity. It is shown that this process is strictly connected to the entropy decrease of compac…
Extra dimensions as a source of the electroweak model
S. V. Bolokhov, K. A. Bronnikov, S. G. Rubin
The Higgs boson of the Standard model is described by a set of off-diagonal components of the multidimensional metric tensor, as well as the gauge fields. In the low-energy limit,…
On the Origin of Gauge Symmetries and Fundamental Constants
S. G. Rubin
A statistical mechanism is proposed for symmetrization of an extra space. The conditions and rate of attainment of a symmetric configuration and, as a consequence, the appearance o…
Multidimensional world, inflation and modern acceleration
K. A. Bronnikov, S. G. Rubin, I. V. Svadkovsky
Starting from pure multidimensional gravity with curvature-nonlinear terms but no matter fields in the initial action, we obtain a cosmological model with two effective scalar fiel…
