A Central Charge for sub-AdS Holography
Abir Ghosh, Chethan Krishnan, Adinath Mahalingam
We synthesize and sharpen various observations about sub-AdS holography in the literature to associate a central charge to sub-AdS scales of AdS x geometries. A key ingredient…
Holomorphic Factorization at the Quantum Horizon
Chethan Krishnan, Pradipta S. Pathak
We identify a horizon-skimming limit under which wave equations around large classes of black holes allow a determination of their low-lying (quasi-)degenerate normal modes. Buildi…
A Bottom-Up Approach to Black Hole Microstates
Vaibhav Burman, Chethan Krishnan
In arXiv:2312.14108, we argued that a sliver at the black hole mass in the Hilbert space of a quantum field theory on an AdS black hole with a stretched horizon, has many desirable…
Young Black Holes Have Smooth Horizons: A Swampland Argument
Chethan Krishnan, Ranjini Mondol
It has been suggested that black hole microstates in string theory may have "no interiors". The arguments of arXiv:2312.14108 suggest that even if this were the case, conventional…
