论文摘要
我们采用了不受管制的计算，在保姆背景上从重力中引力自我能源来推断重归于结果的结果。这用于量化线性化的爱因斯坦方程。我们为代表对静态质量质量的重力响应的电势求解该方程。我们发现，对牛顿电位和重力转移的较大空间和时间对数校正。尽管被微小环计数的参数抑制，但这些校正导致扰动理论在大距离和较晚的时间分解。另一个有趣的事实是，重力诱导多达三个大对数，而一个无质量的，微小的耦合标数的环形循环仅产生一个大的对数。这与重力量模式函数的校正是一致的：重力循环诱导两个大对数，而标量环不给予。
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.
