摘要:

本文计算了四次标量场自相互作用标量-张量引力的单圈有效势,直到一阶后闵可夫斯基阶。势在强场区产生不稳定性,这是有效理论所预期的。根据模型参数,不稳定区域可以在强场区域中呈指数地远离。模型的通货膨胀的情况下可能的应用突出。结果表明,该模型可以进入慢滚区与一定的参数设置。

英文摘要:

One-loop effective potential of scalar-tensor gravity with a quartic scalar field self-interaction is evaluated up to first post-Minkowskian order. The potential develops an instability in the strong field regime which is expected from an effective theory. Depending on model parameters the instability region can be exponentially far in a strong field region. Possible applications of the model for inflationary scenarios are highlighted. It is shown that the model can enter the slow-roll regime with a certain set of parameters.
