论文摘要
时变Hubble功能的经典Friedman方程$ h $，深色能量和物质密度夫妇到量化大型模式的量化场方程$ M \ gg H $。在数值求解这些方程式上，我们显示了微观时间尺度$ {\ MATHCAL O}（m^{ - 1}）$中的粒子 - 抗粒子对产生和振荡。以宏观时间刻度$ {\ Mathcal O}（H^{ - 1}）$形成一个巨大的血浆状态。它的密度和压力引入了弗里德曼方程中物质和暗能量密度的相互作用。重新加热后，我们表明，负暗能量沿辐射时期的辐射能追踪。这种跟踪动力学结束，黑暗能量在时代变得积极。这些物质转化为暗能量，其当前值是可比的，这解释了宇宙的巧合。结果，提倡一类有效的相互作用的暗能模型来面对宇宙学观察。
The classical Friedman equations of time-varying Hubble function $H$, dark-energy and matter densities couple to quantised field equations for massive modes $M\gg H$. Numerically solving these equations, we show the particle-antiparticle pairs production and oscillation in microscopic time scale ${\mathcal O}(M^{-1})$. A massive pair plasma state is formed in macroscopic time scale ${\mathcal O}(H^{-1})$. Its density and pressure introduce the interaction of matter and dark energy densities in the Friedman equations. Focusing on epochs after reheating, we show that the negative dark energy tracks down the radiation energy in the radiation epoch. Such tracking dynamics ends, and dark energy becomes positive in the matter epoch. The matter converts to dark energy, and their present values are comparable, explaining the cosmic coincidence. As a result, a class of effective interacting dark energy models is advocated to confront cosmological observations.
