引力有效场论中的黑洞引力波

Black Hole Gravitational Waves in the Effective Field Theory of Gravity

Claudia de Rham, Jérémie Francfort, Jun Zhang

摘要:

我们研究了引力波在低能量有效场论中的黑洞背景下的传播,其中来自重场的影响被高维曲率算子捕获。根据积分出来的粒子的自旋,与其他物种观察到的因果结构相比,低能量下引力波的速度可以是超光速或亚光速。然而有趣的是,引力波在黑洞视界总是精确的光速,这意味着视界对所有物种都是相同的定义。我们进一步计算了高维曲率算符对拟正规频率的修正,并着重讨论了低能有效场对拟正规频率的修正。

英文摘要:

We investigate the propagation of gravitational waves on a black hole background within the low energy effective field theory of gravity, where effects from heavy fields are captured by higher dimensional curvature operators. Depending on the spin of the particles integrated out, the speed of gravitational waves at low energy can be either superluminal or subluminal as compared to the causal structure observed by other species. Interestingly however, gravitational waves are always exactly luminal at the black hole horizon, implying that the horizon is identically defined for all species. We further compute the corrections on quasinormal frequencies caused by the higher dimensional curvature operators and highlight the corrections arising from the low energy effective field.
