The path integral of 3D gravity near extremality; or, JT gravity with defects as a matrix integral

Henry Maxfield et al.

Summary: The proposal suggests including a new class of topologies in the path integral of three-dimensional pure gravity to address negative aspects in the spectrum, leading to a nonperturbative shift of the BTZ extremality bound. A two-dimensional calculation using dimensionally reduced theory can capture the primary effects in the near extremal limit, as demonstrated through a study of a related two-dimensional theory of Jackiw-Teitelboim gravity with dynamic defects, which is shown to be equivalent to a matrix integral.

Free partition functions and an averaged holographic duality

Nima Afkhami-Jeddi et al.

Summary: The study focuses on the torus partition functions of free bosonic CFTs in two dimensions, showing that integrating over Narain moduli defines an ensemble-averaged free CFT and the averaged partition function can be reinterpreted as a sum over topologies in three dimensions. This leads to the conjecture that an averaged free CFT in two dimensions is holographically dual to an exotic theory of three-dimensional gravity with U(1)(c)xU(1)(c) symmetry and a composite boundary graviton. Additionally, general constraints on the spectral gap of free CFTs are obtained for small central charge c, Narain compactifications with a large gap are constructed, and an analytic bootstrap functional corresponding to a single self-dual boson is found using the spinning modular bootstrap.

Low-temperature entropy in JT gravity

Oliver Janssen et al.

Summary: The study examines the relationship between entropy and temperature in ensembles of specific types of random matrices, as well as the correspondence between JT gravity and the double-scaling limit.

Free energy from replica wormholes

Netta Engelhardt et al.

Summary: The text discusses the challenge of Euclidean wormholes to the standard quantum mechanical interpretation and suggests that gravitational path integral computes the ensemble average of multiple theories. It highlights the contribution of connected topologies to the free energy and evidence of replica symmetry breaking in both JT gravity and a simplified version of CGHS. The insights about ensemble averaging in gravity from this perspective are also discussed.
