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

Conformal field theories have been long known to describe the fascinating universal physics
of scale invariant critical points. They describe continuous phase transitions in fluids …

A bstract We describe in more detail the general relation uncovered in our previous work
between boundary correlators in de Sitter (dS) and in Euclidean anti-de Sitter (EAdS) space …

A bstract It is a long-standing conjecture that any CFT with a large central charge and a large
gap∆ gap in the spectrum of higher-spin single-trace operators must be dual to a local …

Fundamental principles of local quantum field theory or of quantum gravity can enforce
consistency requirements on the space of consistent low-energy effective field theories. We …

A bstract We give a detailed account of the methods introduced in [1] to calculate
holographic four-point correlators in IIB supergravity on AdS 5× S 5. Our approach relies …

A bstract We analyse the double-discontinuities of the four-point correlator of the stress-
tensor multiplet in N= 4 SYM at large t'Hooft coupling and at order 1/N 4, as a way to access …

A bstract We prove a conjectured lower bound on< T__ (x)> ψ in any state ψ of a CFT on
Minkowski space, dubbed the Quantum Null Energy Condition (QNEC). The bound is given …

A bstract In this paper, we explore supersymmetric and 2d analogs of the SYK model. We
begin by working out a basis of (super) conformal eigenfunctions appropriate for expanding …

A bstract We study propagation of a probe particle through a series of closely situated
gravitational shocks. We argue that in any UV-complete theory of gravity the result does not …
