Soliton foam formation in the early Universe
A. A. Kirillov, B. S. Murygin, V. V. Nikulin
The formation of composite solitons produced by scalar fields without thermal phase transitions in the early Universe is considered. We present numerical simulations of the formati…
Possible scenario of relic wormhole formation
A. A. Kirillov, E. P. Savelova
It is shown that in the presence of virtual wormholes, the vacuum is unstable, which leads to a series of phase transitions in the early Universe. Then the standard Kibble scenario…
Dynamics and merger rate of primordial black holes in a cluster
Viktor D. Stasenko, Alexander A. Kirillov, Konstantin M. Belotsky
The PBHs clusters can be source of gravitational waves, and the merger rate depends on the spatial distribution of PBHs in the cluster which changes over time. It is well known tha…
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…
On mass spectra of primordial black holes
Alexander A. Kirillov, Sergey G. Rubin
Evidences for the primordial black holes (PBH) presence in the early Universe renew permanently. New limits on their mass spectrum challenge existing models of PBH formation. One o…
The Merger Rate of Black Holes in a Primordial Black Hole Cluster
Viktor D. Stasenko, Alexander A. Kirillov
In this paper, the merger rate of black holes in a cluster of primordial black holes (PBHs) is investigated. The clusters have characteristics close to those of typical globular st…
