Primordial black holes
V. I. Dokuchaev, Yu. N. Eroshenko, V. V. Nikulin +3
Primordial black holes, whose formation in the early Universe was first hypothesized by Ya.B.~Zel'dovich and I.D.~Novikov in 1966 (the text of this pioneering article is provided i…
Compact extra dimensions as the source of primordial black holes
Valery V. Nikulin, Maxim A. Krasnov, Sergey G. Rubin
We discuss the model of the primordial black holes formation at the reheating stage. These small massive black holes appear due to specific properties of the compact extra dimensio…
Cosmological baryon/lepton asymmetry in terms of Kaluza-Klein extra dimensions
Valery V. Nikulin, Sergey G. Rubin
In this article, we discuss the mechanism for generating the lepton/baryon number and its subsequent conservation based on extradimensional evolution. The internal angular momentum…
Cosmological Formation of (2+1)-Dimensional Soliton Structures in Models Possessing Potentials with Local Peaks
A. A. Kirillov, B. S. Murygin, V. V. Nikulin
Production of domain walls and string-like solitons in the model with two real scalar fields and potential with at least one saddle point and a local maximum is considered. The mod…
Cosmological accumulation of conserved numbers in Kaluza-Klein theories
Valery Nikulin
We develop a new mechanism for the accumulation of conserved numbers in the early Universe in Kaluza-Klein-like theories. The relaxation of the primordial extra space perturbations…
Formation of conserved charge at the de Sitter space
V. V. Nikulin, S. G. Rubin, P. M. Petryakova
The article considers a new mechanism of charge accumulation in the early Universe in theories with compact extra dimensions. The relaxation processes in the extra space metric tha…
