非最小自然暴胀激发的标量场模型的协变量子修正

Covariant quantum corrections to a scalar field model inspired by nonminimal natural inflation

Sandeep Aashish, Sukanta Panda

摘要:

我们计算了受最近提出的非最小自然暴胀模型启发的标量场模型的协变单圈量子引力有效作用量。我们的计算是微扰的,在这个意义上,有效的行动是评估的顺序的背景场,周围的闵可夫斯基背景。考虑到有限修正的有效势已被评估。单圈修正的数量级估计表明,引力和非引力修正具有相同或相当的量值。

英文摘要:

We calculate the covariant one-loop quantum gravitational effective action for a scalar field model inspired by the recently proposed nonminimal natural inflation model. Our calculation is perturbative, in the sense that the effective action is evaluated in orders of background field, around a Minkowski background. The effective potential has been evaluated taking into account the finite corrections. An order-of-magnitude estimate of the one-loop corrections reveals that gravitational and non-gravitational corrections have same or comparable magnitudes.
