3D de Sitter from complex Virasoro TQFT: Observers and knots
Jeevan Chandra, Diego Liska, Boris Post
The Euclidean saddles of 3D Einstein gravity with positive cosmological constant are spherical three-manifolds. When one adds a heavy observer, the backreacted saddles are spherica…
Positivity constraints on the dynamics of cusped impurities in CFTs
Jeevan Chandra
The cusp anomalous dimension is the universal logarithmic contribution to the free energy of a line defect with a cusp, and provides a useful observable characterizing defect dynam…
Elastic stiffness of three-dimensional black holes and wormholes from Liouville line defects
Jeevan Chandra, Boris Post
We study elastic deformations of thin-shell black holes and wormholes in AdS gravity. These geometries are sourced by line defects in the dual conformal field theory, and their…
Line Defects in Liouville Conformal Field Theory: Localized Cosmological Constants and Decohered Hyperbolic Geometries
Ahmed I. Abdalla, Jeevan Chandra, Yifan Wang
The study of quantum impurities has long been a central and inspiring theme in quantum many-body physics. Localized impurities are modeled by line defects in quantum field theory.…
Statistics in 3d gravity from knots and links
Jeevan Chandra
In recent years, there has been remarkable progress in evaluating wormhole amplitudes in 3d Einstein gravity with negative cosmological constant and matching them to statistics of…
Rademacher expansion of modular integrals
Marco Maria Baccianti, Jeevan Chandra, Lorenz Eberhardt +2
We develop a method to evaluate integrals of non-holomorphic modular functions over the fundamental domain of the torus with modular parameter analytically. It proceeds in two…
Euclidean wormholes in holographic RG flows
Jeevan Chandra
We describe a one-parameter family of Euclidean wormhole solutions with the topology of a compact hyperbolic space times an interval in Einstein gravity minimally coupled to a mass…
Statistics of three-dimensional black holes from Liouville line defects
Jeevan Chandra, Thomas Hartman, Viraj Meruliya
Black holes and wormholes in the gravitational path integral can be used to calculate the statistics of heavy operators. An explicit example in higher dimensions is provided by thi…
Euclidean wormholes for individual 2d CFTs
Jeevan Chandra
We interpret appropriate families of Euclidean wormhole solutions of AdS gravity in individual 2d CFTs as replica wormholes described by branching around the time-symmetric app…
Toward random tensor networks and holographic codes in CFT
Jeevan Chandra, Thomas Hartman
In holographic CFTs satisfying eigenstate thermalization, there is a regime where the operator product expansion can be approximated by a random tensor network. The geometry of the…
Coarse graining pure states in AdS/CFT
Jeevan Chandra, Thomas Hartman
We construct new Euclidean wormhole solutions in AdS(d+1) and discuss their role in UV-complete theories, without ensemble averaging. The geometries are interpreted as overlaps of…
Semiclassical 3D gravity as an average of large-c CFTs
Jeevan Chandra, Scott Collier, Thomas Hartman +1
A two-dimensional CFT dual to a semiclassical theory of gravity in three dimensions must have a large central charge and a sparse low energy spectrum. This constrains the OPE c…
