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.…
