Description
I will present the analytical bootstrap approach to thermal holographic two-point functions, based on the interplay between their analytic structure, the Kubo–Martin–Schwinger (KMS) condition, and multi–stress tensor OPE coefficients determined from the dual AdS description. The analysis focuses on two-point functions of identical scalar operators with integer conformal dimensions at zero spatial separation. In black brane backgrounds, I show that holographic thermal correlators naturally decompose into three distinct contributions: a principal term, which can be computed exactly, and two subleading terms—regularized and arcs contributions—whose behavior is controlled by the asymptotics of OPE coefficients. I will demonstrate the method by focusing on the example
$\Delta_\phi=3$, showing that the resulting analytical solution agrees to good approximation with numerical solutions of the bulk wave equation.
