标题： Dark energy due to quantum corrections to effective potential

摘要： 在本文中，我们计算了暴胀宇宙学不同模型中的有效势的量子修正。 我们表明，量子修正会导致初始势的修改，使其在最小值处的值升高，这可以解释为宇宙常数/暗能量。 我们专注于$\alpha$-吸引子模型，并表明可以自然地得到宇宙常数的小值。 在指数势模型中，同样的机制会修改当前暗能量的值。 显示英文摘要

摘要： 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 $\alpha$-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.
