摘要

本文计算了不同暴胀宇宙学模型中有效势的量子修正。我们表明，量子修正导致初始势的修改，使其值在最小值处上升，这可以解释为宇宙常数/暗能量。我们集中讨论了α-吸引子的模型，并表明人们可以很自然地得到很小的宇宙常数值。在精粹模型中，同样的机制改变了当前暗能量的值。

Dark energy due to quantum corrections to effective potential

In this paper we calculate quantum corrections to the effective potential in different models of inflationary cosmology. We show that quantum corrections lead to a modification of the initial potential uplifting its value at the minimum, which can be interpreted as a cosmological constant/dark energy. We concentrate on the models of α-attractors and show that one can naturally get small values of the cosmological constant. In the model of quintessence, the same mechanism modifies the value of dark energy at the present time.
