Yu. G. Ignat'ev, D. Yu. Ignatyev, and A. R. Samigullina A Macroscopic View of the Standard Cosmological Model //Gravitation and Cosmology, 2018, Vol. 24, No. 2, pp. 148–153

Аннотация

Averaging of the dynamic functions of the standard cosmological model (SCM) at its early stage with the dominance of a scalar field is carried out. It is shown that microscopic oscillations with Compton period provide a major contribution to the macroscopic energy density of the scalar field at large times at this stage. In this case, the effective equation of state of the scalar field oscillates between the inflationary and the extremely rigid ones, while the macroscopic equation of state, obtained by averaging over fast oscillations of the scalar field, is nonrelativistic.
