Формирование солитонных структур в ранней Вселенной и астрофизические проявления первичных черных дыр
Cosmological Formation of (2+1)-Dimensional Soliton Structures in Models Possessing Potentials with Local Peaks
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 model is regarded as 2-dimensional spatial slices of 3-dimensional entire structures. It is shown that, in the early Universe, both types of solitons may appear. In addition, the qualitative estimate of the domain walls and strings formation probabilities is presented. It is found that the probability of the formation of string-like solitons is suppressed compared to that of domain walls.
The mechanism of domain walls and strings formation in the early Universe
© Published under licence by IOP Publishing Ltd.A classical dynamics of two real scalar fields within a model with a saddle point potential in (2+1)-space-Time is discussed. We show that in this model, solitons may be formed both as domain walls and strings in three dimensional physical space. The formation and evolution of these field configurations are considered.
