Minkowski Space holography and Radon transform
Samrat Bhowmick, Koushik Ray
We relate a free scalar field in the Minkowski spacetime with a scalar field with a certain scaling dimension on a sphere of codimension two. This is realised by first performing a…
Holography in de Sitter and anti-de Sitter Spaces and Gel'fand Graev Radon transform
Samrat Bhowmick, Koushik Ray, Siddhartha Sen
Bulk reconstruction formulas similar to HKLL are obtained for de Sitter and anti-de Sitter spaces as the inverse Gel'fand Graev Radon transform. While these generalize our previous…
Holography on local fields via Radon Transform
Samrat Bhowmick, Koushik Ray
We define Radon transform and its inverse on the two-dimensional anti-de Sitter space over local fields using a novel construction through a quadratic equation over the local field…
Bulk reconstruction in AdS and Gel'fand-Graev-Radon Transform
Samrat Bhowmick, Koushik Ray, Siddhartha Sen
The bulk reconstruction formula for a Euclidean anti-de Sitter space is directly related to the inverse of the Gel'fand-Graev-Radon transform. Correlation functions of a conformal…
Entanglement entropy and kinematic space in BCFT and RG flow
Samrat Bhowmick, Suchetan Das, Bobby Ezhuthachan
The relation between kinematic space metric and entanglement entropy provides us with a differential equation for entanglement entropy. For BCFT on upper half plane we solve this e…
Towards Timelike Singularity via AdS Dual
Samrat Bhowmick, Soumyabrata Chatterjee
It is well known that Kasner geometry with space-like singularity can be extended to bulk AdS-like geometry, furthermore one can study field theory on this Kasner space via its gra…
