论文摘要
在原始的宇宙前（后）通货膨胀时代，可能存在冷气，辐射和通货膨胀后宇宙学后早期宇宙的早期宇宙的阶段。我表明，在Baryonic时期，量子真空是独一无二的。通过对经典时空中具有最大符号对称性的大规模最小耦合标量场进行标准量化方案，我证明了标量模式具有有效的质量$ m_ {eff}^2 \ off 0 $（或$ m_ {eff}^2 \ listant $）。当保形时间$η$保持到通货膨胀结束时间$η=η_c$时，该参数已验证。重型物质的能量密度在通货膨胀边界上有所不同，并在未来的未来消失。此外，我认为，当辐射是与早期宇宙宇宙常数，标量场$ M \ propto \sqrtλ$的较早竞争中的主要竞争中，当辐射是主要竞争中的主要部分时，也提供了独特的量子真空。原因是有效质量最终消失了。一个显着的观察是，所有其他可能的真空均以永恒的“挤压”状态。
In a primordial universe pre(post)-inflationary era , there could be phases of early universe made of cold gas baryons, radiation and early post inflationary cosmological constant. I showed that in the baryonic epoch, the quantum vacuum is unique. By using the standard quantization scheme for a massive minimally coupled scalar field with maximal conformal symmetry in the classical spacetime, I demonstrated that the scalar modes had an effective mass $m_{eff}^2\approx 0$ (or $m_{eff}^2\approx constant$). This argument validated when the conformal time $η$ kept so close to the inflation ending time $η=η_c$. The energy density of the baryonic matter diverged at the inflation border and vanishes at the late time future. Furthermore I argued that at very early accelerating epoch when the radiation was the dominant part in the close competition with the early time cosmological constant, fine tuned mass of the scalar field $m\propto \sqrtΛ$ also provided a unique quantum vacuum. The reason is that the effective mass eventually is vanished. A remarkable observation was that all the other possible vacuum states "squeezed" eternally.
