Statistical Cosmological Fermion Systems with Phantom Scalar Interaction of Particles

Resumo

The article represents a research of the cosmological evolution of fermion statistical systems with phantom scalar interaction where the “kinetic” term’s contribution to the total energy of a scalar field is negative. As a result of analytical and numerical simulation of such systems, we have revealed the existence of four possible scenarios depending on the system’s parameters and the initial conditions. Among them are scenarios with an early, intermediate and late nonrelativistic stages of the cosmological evolution, all of which also have a necessary inflationary stage. This paper contains only a small part of the research results. In a more complete form, they are presented in arXiv: 1608.05020 [1].
