More than 65 years ago, John Wheeler suggested that quantum uncertainties of the metric
would be of order one at the Planck scale, leading to large fluctuations in spacetime …

In this review article, we describe some of the recent progress towards the construction and
analysis of three-charge configurations in string theory and supergravity. We begin by …

A bstract Recent developments involving JT gravity in two dimensions indicate that under
some conditions, a gravitational path integral is dual to an average over an ensemble of …

A bstract We study the torus partition functions of free bosonic CFTs in two dimensions.
Integrating over Narain moduli defines an ensemble-averaged free CFT. We calculate the …

A bstract In the AdS/CFT correspondence, amplitudes associated to connected bulk
manifolds with disconnected boundaries have presented a longstanding mystery. A possible …

A bstract We study families of two dimensional quantum field theories, labeled by a
dimensionful parameter μ, that contain a holomorphic conserved U (1) current J (z). We …

We propose a dual non-perturbative description for maximally extended Schwarzschild Anti-
de-Sitter spacetimes. The description involves two copies of the conformal field theory …

A bstract Two-dimensional conformal field theories exhibit a universal free energy in the
high temperature limit T→∞, and a universal spectrum in the Cardy regime, Δ→∞. We show …

Ryu and Takayanagi conjectured a formula for the entanglement (von Neumann) entropy of
an arbitrary spatial region in an arbitrary holographic field theory. The von Neumann entropy …

We construct a unitary, modular-invariant torus partition function of a two-dimensional
conformal field theory with a Virasoro primary spectral gap of Δ*=[(c-1)/12] above the …
