Conformally mapping HKLL to flat space
Nirmalya Kajuri, Rhitaparna Pal
We study two conformal images of the HKLL reconstruction problem for a conformally coupled scalar on AdS. The first mapping is to a Dirichlet problem on one half of the Einstei…
Asymptotic Algebras and Holography of Information in CGHS Model
Waheed A. Dar, Nirmalya Kajuri, Rinkesh Panigrahi
Holography of Information (HoI) and the island formula are two recent approaches to the black hole information loss paradox that yield different Page curves. The difference between…
Black Hole Interior Operators and Dilatation Symmetry in Planar Black Branes
Nirmalya Kajuri
Planar AdS black branes have a scaling symmetry that maps a brane solution at one temperature to a solution at another. It is natural to expect that boundary representations of bul…
Holographic One-Point Function and Geodesics in SdS
Arundhati Goldar, Nirmalya Kajuri, Rhitaparna Pal
Grinberg and Maldacena showed that heavy thermal one-point functions in AdS/CFT can encode complex geodesics reaching a black hole singularity. We study the de Sitter analogue in t…
Momentum Space Correlation Functions in 2D Galilean Conformal Algebra
Anchita Chetia, Nirmalya Kajuri, Chandra Prakash
Galilean Conformal Algebra (GCA) arises as a controlled nonrelativistic limit of the relativistic conformal algebra. In this paper, we initiate the study of momentum space correlat…
Geodesics, One Point Functions and Black Hole Perturbations
Parijat Dey, Arundhati Goldar, Nirmalya Kajuri
Holographic black holes exhibit a striking relation between thermal boundary one-point functions and bulk geodesic lengths. In the large conformal-dimension limit, the one-point fu…
When Black Holes Relax in a Cold Bath: Evolving Page Curves for Black Holes Coupled to Cooling Baths
Waheed A. Dar, Nirmalya Kajuri, Rinkesh Panigrahi
We consider scenarios where Jackiw-Teitelboim black holes are attached to baths whose temperatures can be manipulated externally. We consider the bath to be cooled continuously and…
Hawking Radiation in Jackiw-Teitelboim Gravity
Waheed A. Dar, Prince A. Ganai, Nirmalya Kajuri
In this paper, we study Hawking radiation in Jackiw-Teitelboim gravity for minimally coupled massless and massive scalar fields. We employ a holography-inspired technique to derive…
Bulk reconstruction in 2D multi-horizon black hole
Parijat Dey, Nirmalya Kajuri, Rhitaparna Pal
The goal of the bulk reconstruction program is to construct boundary representations of fields in asymptotically Anti-de Sitter spacetimes. In this paper, we extend the program by…
Bulk Reconstruction in De Sitter Spacetime
Arundhati Goldar, Nirmalya Kajuri
The bulk reconstruction program involves expressing local bulk fields as non-local operators on the boundary. It was initiated in the context of AdS/CFT correspondence. Attempts to…
Bulk reconstruction and Bogoliubov transformations in AdS
Parijat Dey, Nirmalya Kajuri
In the bulk reconstruction program, one constructs boundary representations of bulk fields. We investigate the relation between the global/Poincare and AdS-Rindler representations…
Symmetry transformation of subregion bulk representations
Nirmalya Kajuri
Different AdS-Rindler wedges can be mapped to each other using bulk isometries. In this paper we address how the boundary representations corresponding to the AdS-Rindler wedges tr…
Bulk reconstruction in rotating BTZ black hole
Nirmalya Kajuri
The bulk reconstruction program aims to obtain representations of bulk fields as operators in the boundary CFT. In this paper we extend the program by obtaining the boundary repres…
Lectures on Bulk Reconstruction
Nirmalya Kajuri
If the AdS/CFT conjecture holds, every question about bulk physics can be answered by the boundary CFT. But we still don't know how to translate all the questions about bulk physic…
Subregion bulk reconstruction and symmetries
Nirmalya Kajuri
How do subregion boundary representations transform under conformal transformations? In this paper we conjecture a transformation rule and provide evidence for it. We also show how…
Bulk-boundary dictionary for a non local bulk field
Nirmalya Kajuri, Gaurav Narain
AdS/CFT correspondence gives us a bulk-boundary dictionary between CFT operators and local fields in the bulk. Can a bulk-boundary dictionary exist for a non local bulk field? In t…
Entanglement entropy of non-local theories in AdS
Gaurav Narain, Nirmalya Kajuri
We investigate the effect of non-locality on entanglement entropy in anti-de Sitter space-time. We compute entanglement entropy of a nonlocal field theory in anti-de Sitter space-t…
Non-local scalar field on deSitter and its infrared behaviour
Gaurav Narain, Nirmalya Kajuri
We investigate free non-local massless and massive scalar field on deSitter (dS) space-time. We compute the propagator for the non-local scalar field for the corresponding theories…
