Cosmological evolutions of a completely degenerate Fermi system with scalar interactions between particles

Yu.G. Ignatyev and R.A. Miftakhov1

Abstract

Cosmological solutions of Einstein's equations for equilibrium statistical systems of particles with scalar interaction are studied. It is shown that the scalar field can effectively change the equation of state of a statistical system, which makes possible a secondary acceleration of the cosmological expansion.
