摘要：

We study the classical Friedman equations for the time-varying cosmological term & Acirc; and Hubble function H, together with quantised field equations for the production of massive M & raquo; H particles, namely, the & Acirc;CDM scenario of dark energy and matter interactions. Classical slow components O(H-1) are separated from quantum fast compo-nents O(M-1). The former obeys the Friedman equations, and the latter obeys a set of nonlinear differential equations. Numerically solving equations for quantum fast components, we find the production and oscillation of massive particle-antiparticle pairs in microscopic time scale O(M-1). Their density and pressure averages over microscopic time do not vanish. It implies the formation of a massive pair plasma state in macroscopic time scale O(H-1), whose effective density and pressure contribute to the Friedman equations. Considering the inflation driven by the time-varying cosmo-logical term and slowed down by the massive pair plasma state, we obtain the relation of spectral index and tensor-to-scalar ratio in agreement with recent observations. We discuss the singularity-free pre-inflation, the CMB large-scale anomaly, and dark-matter density perturbations imprinting on power spectra.
