Abstract We study simple examples of ensemble-averaged holography in free compact boson CFTs with rational values of the radius squared. These well-known rational CFTs have an extended chiral algebra generated by three currents. We consider the modular average of the vacuum character in these theories, which results in a weighted average over all modular invariants. In the simplest case, when the chiral algebra is primitive (in a sense we explain), the weights in this ensemble average are all… 
Factorization and Global Symmetries in Holography
We consider toy models of holography arising from 3d Chern-Simons theory. In this context a duality to an ensemble average over 2d CFTs has been recently proposed. We put forward an alternative
Baby universes, ensemble averages and factorizations with matters
We investigate 2D topological gravity theories with matter fields turned on. We compute correlators of boundary creation operators with extra matter insertions. We provide a systematic procedure to


Wormholes and spectral statistics in the Narain ensemble
Abstract We study the spectral statistics of primary operators in the recently formulated ensemble average of Narain’s family of free boson conformal field theories, which provides an explicit
Comments on the holographic description of Narain theories
The hypothesis that in the large central charge limit the density of states of any Narain theory is bounded by below by the densityof states of U(1) gravity is formed, which implies that the maximal value of the spectral gap for primary fields is ∆1 = c/(2πe).
Poincaré series, 3d gravity and averages of rational CFT
Abstract: We investigate the Poincaré series approach to computing 3d gravity partition functions dual to Rational CFT. For a single genus-1 boundary, we show that for certain infinite sets of
Narain to Narnia
We generalize the holographic correspondence between topological gravity coupled to an abelian Chern-Simons theory in three dimensions and an ensemble average of Narain’s family of massless free
Light-cone modular bootstrap and pure gravity
We explore the large spin spectrum in two-dimensional conformal field theories with a finite twist gap, using the modular bootstrap in the light-cone limit. By recursively solving the modular
Kac-Moody and Virasoro characters from the perturbative Chern-Simons path integral
A bstractWe evaluate to one loop the functional integral that computes the partition functions of Chern-Simons theories based on compact groups, using the background field method and a covariant
Averaging over moduli in deformed WZW models
Abstract WZW models live on a moduli space parameterized by current-current deformations. The moduli space defines an ensemble of conformal field theories, which generically have N abelian conserved
Quantum gravity partition functions in three dimensions
We consider pure three-dimensional quantum gravity with a negative cosmological constant. The sum of known contributions to the partition function from classical geometries can be computed exactly,
Poincaré series, 3D gravity and CFT spectroscopy
A bstractModular invariance strongly constrains the spectrum of states of two dimensional conformal field theories. By summing over the images of the modular group, we construct candidate CFT
The Gravity Dual of the Ising Model
We evaluate the partition function of three dimensional theories of gravity in the quantum regime, where the AdS radius is Planck scale and the central charge is of order one. The contribution from
