强耦合热化CFT中的谱函数

The spectral function in a strongly coupled, thermalising CFT

Alice Bernamonti, Ben Craps, Joris Vanhoof

摘要:

与涨落耗散定理有关,我们讨论了谱函数和有效温度随时间变化的概念。从arXiv:1212.6066扩展最近的结果,我们在一个二维热化CFT对偶AdS 3-Vaidya时空中计算出这些量,该时空在早期的黑膜几何和后期的更高温度的黑膜之间插值。计算在引力全息对偶中进行,采用测地线近似和非标准解析延拓。

英文摘要:

In relation to the fluctuation-dissipation theorem, we discuss a time-dependent notion of spectral function and effective temperature. Extending recent results from arXiv:1212.6066, we work out these quantities in a two-dimensional thermalising CFT dual to AdS3-Vaidya spacetime which interpolates between a black brane geometry at early times and a higher temperature black brane at late times. The computation is carried out in the gravitational holographic dual in the geodesic approximation and using a non-standard analytic continuation.
