The spectral function in a strongly coupled, thermalising CFT
Boekbijdrage - Boekhoofdstuk Conferentiebijdrage
In relation to the fluctuation-dissipation theorem, we discuss a time-dependent notion of spectral
function and effective temperature. Extending recent results from [1], 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.
