标题： How Inflationary Gravitons Affect the Force of Gravity

摘要： 我们采用一种不受约束的计算，在德西特背景上从引力子计算引力子自能，以推导出重整化结果。 这用于对线性化的爱因斯坦方程进行量子修正。 我们求解该方程，以得到表示对静态点质量的引力响应的势函数。 我们发现牛顿势和引力位移存在大的空间和时间对数修正。 尽管这些修正被一个微小的环计数参数所抑制，但它们导致在大距离和晚时间时微扰理论失效。 另一个有趣的现象是，引力子可以引起多达三个大的对数修正，而无质量、最小耦合标量的环仅产生一个大的对数修正。 这与引力子模函数的修正一致：引力子环引起两个大的对数修正，而标量环则没有。 显示英文摘要

摘要： We employ an unregulated computation the graviton self-energy from gravitons on de Sitter background to infer the renormalized result. This is used to quantum-correct the linearized Einstein equation. We solve this equation for the potentials which represent the gravitational response to static, point mass. We find large spatial and temporal logarithmic corrections to the Newtonian potential and to the gravitational shift. Although suppressed by a minuscule loop-counting parameter, these corrections cause perturbation theory to break down at large distances and late times. Another interesting fact is that gravitons induce up to three large logarithms whereas a loop of massless, minimally coupled scalars produces only a single large logarithm. This is in line with corrections to the graviton mode function: a loop of gravitons induces two large logarithms whereas a scalar loop gives none.
