论文摘要
在早期的宇宙中，暗能量可能具有不可忽略的贡献。如果这种暗能量对应于早期的宇宙常数，则会导致较晚的巨大深色能量密度，该密度远大于宇宙当前扩张的预期。使用序言与暗物质的共形耦合，并基于筛选模型，我们提出了一个过程，以将早期的暗能量降低到后期的最终价值。早期和晚期的黑暗能量可以通过这种方式统一。
In the early Universe, dark energy may have a non-negligible contribution. If this dark energy corresponds to an early cosmological constant, it leads to a late-time huge dark energy density which is much larger than what is expected for the current expansion of the Universe. Using a conformal coupling of the quintessence to the dark matter, and based on the screening models, we propose a process to reduce the early dark energy to its ultimate value in the late time. Early and late time dark energies can be unified in a single component, in this way.
