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 conjecture a sharp bound on the rate of growth of chaos in thermal quantum
systems with a large number of degrees of freedom. Chaos can be diagnosed using an out …

A bstract We use holography to study sensitive dependence on initial conditions in strongly
coupled field theories. Specifically, we mildly perturb a thermofield double state by adding a …

A bstract We argue that every CFT contains light-ray operators labeled by a continuous spin
J. When J is a positive integer, light-ray operators become integrals of local operators over a …

A bstract In [1] we gave a precise holographic calculation of chaos at the scrambling time
scale. We studied the influence of a small perturbation, long in the past, on a two-sided …

A bstract We consider higher derivative corrections to the graviton three-point coupling
within a weakly coupled theory of gravity. Lorentz invariance allows further structures …

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 …

We study chaotic dynamics in two-dimensional conformal field theory through out-of-time
order thermal correlators of the form $\langle W (t) VW (t) V\rangle $. We reproduce bulk …

A bstract We consider several aspects of unitary higher-dimensional conformal field theories
(CFTs). We first study massive deformations that trigger a flow to a gapped phase. Deep …
