Abstract:
As the red shift shows no sign of oscillatory behavior in an expanding universe we postulate that the energy ωk of a scalar field does not oscillate in such a universe. In the massive case, expanding the differential equation for ωk in mass powers, we find that the nonoscillatory solution coincides with the adiabatic solution up to the m6 order. We also demonstrate that this solution is unique for all the evolution of the universe with cosmological interest. Using the nonoscillatory solution as the one that defines the good vacuum state, we compute the particle and energy creation for a simple model of expanding universe. Both quantities turn out to be finite. © 1986 Plenum Publishing Corporation.
