Motivated by conceptual problems in quantum theories of gravity, the gravitational eikonal
approach, inspired by its electromagnetic predecessor, has been successfully applied to the …

This review aims to offer a pedagogical introduction to the analytic conformal bootstrap
program via a journey through selected topics. We review analytic methods which include …

We present an exact formula for the thermal scalar two-point function in four-dimensional
holographic conformal field theories. The problem of finding it reduces to the analysis of the …

A bstract We study the analytic structure of the heavy-heavy-light-light holographic
correlators in the supergravity approximation of the AdS 3× S 3/CFT 2 duality. As an explicit …

A bstract We explore the implications of stable gravitational orbits around an AdS black hole
for the boundary conformal field theory. The orbits are long-lived states that eventually decay …

A bstract We study black hole linear perturbation theory in a four-dimensional Schwarzschild
(anti) de Sitter background. When dealing with a positive cosmological constant, the …

A bstract Lorentzian correlators of local operators exhibit surprising singularities in theories
with gravity duals. These are associated with null geodesics in an emergent bulk geometry …

In d-dimensional CFTs with a large number of degrees of freedom an important set of
operators consists of the stress tensor and its products, multi stress tensors. Thermalization …

A bstract The eikonal phase which determines the Regge limit of the gravitational scat-tering
amplitude of a light particle off a heavy one in Minkowski spacetimes admits an expansion in …

A bstract We investigate the heavy-light four-point function up to double-stress-tensor,
supplementing 1910.06357. By using the OPE coefficients of lowest-twist double-stress …
