Quantum Gravity from Gluing Consistency: AdS/CFT to Spin-Foams
Chethan Krishnan
We argue that BF theory with gauge group provides a SymTFT ''skeleton'' for building AdS/CFT pairs via gluing consistency as the bootstrap principle, loosel…
Building a Quantum Black Hole Microstate: A Bulk Path Integral for a Heavy Virasoro Primary
Chethan Krishnan, Rajdeep Mitra
Consider level- Chern-Simons theory on a semi-infinite solid cylinder, with a Wilson line in the unitary principal continuous series inserted along the…
Wilson Towers as Local Bulk Fields
Vishal Gayari, Chethan Krishnan
Multi-winding Wilson loops (``Wilson spools'') in 2+1-dimensional gravity can reproduce one-loop partition functions of local free fields in the bulk. Bulk free fields have a secon…
Geodesics from Quantum Field Theory: A Case Study in AdS
Vaibhav Burman, Chethan Krishnan, Livesh Parajuli
Localized one-particle states of a quantum field theory--whether in flat space or on a curved background--are expected to exhibit geodesic motion in an appropriate semiclassical re…
Holography, Brick Wall and a Little Hierarchy Problem
Vishal Gayari, Chethan Krishnan, Pradipta S. Pathak
We propose a heuristic for the brick wall in AdS/CFT: the location where a boundary mode's local bulk energy reaches a (Planckian) UV cut-off. This accomplishes two things: (a) the…
Holography with an Inner Boundary: A Smooth Horizon as a Sum over Horizonless States
Chethan Krishnan, Pradipta S. Pathak
The (holomorphic) partition function of the Euclidean BTZ black hole with boundary modulus , is the -image of the Virasoro vacuum character, . This object…
