标题： A Unified Model of Dark Energy Based on the Mandelstam-Tamm Uncertainty Relation

摘要： 现在普遍认为，暗能量（Lambda项）在宇宙演化的早期（暴胀）阶段和目前都具有关键重要性。 然而，直到现在，对其性质和起源了解甚少。 特别是，Lambda项是否是一个新的基本常数，还是仅仅来自底层场论的有效贡献，仍然不清楚。 在这里，我们表明，解决这个问题的一个非常有前途且普遍的方法可能基于量子力学的Mandelstam-Tamm不确定性关系。 结果，我们得到了在整个宇宙历史中都重要的有效Lambda项。 此外，这种方法需要对一些其他宇宙学参数进行重大重新考虑，例如宇宙的年龄。 显示英文摘要

摘要： It is commonly recognized now that Dark Energy (Lambda-term) is of crucial importance both at the early (inflationary) stage of cosmological evolution and at the present time. However, little is known about its nature and origin till now. In particular, it is still unclear if Lambda-term is a new fundamental constant or represents just an effective contribution from the underlying field theory. Here, we show that a quite promising and universal approach to this problem might be based on the Mandelstam-Tamm uncertainty relation of quantum mechanics. As a result, we get the effective Lambda-term that is important throughout the entire history of the Universe. Besides, such an approach requires a substantial reconsideration of some other cosmological parameters, e.g., the age of the Universe.
