Aspects of Codimension two Holography in de Sitter Space
Kanhu Kishore Nanda, Somnath Porey, Masataka Watanabe +1
Following \cite{Yadav:2024ray} we embark on a further study of the codimension two holography in de Sitter (dS) space. The dimensional bulk dS space is sliced by two end of the…
Index saddle for the D1-D5-P black string and its decoupling limit
Kanhu Kishore Nanda, P Shanmugapriya, Amitabh Virmani
Boruch, Emparan, Iliesiu, and Murthy recently discussed index saddles for 5d black strings, showing that the black string saddle admits a decoupling limit to a complex, finite-temp…
The Thermodynamics of Cosmological Horizons and Their Holographic Description in de Sitter Space
Indranil Dey, Kanhu Kishore Nanda, Akashdeep Roy +2
We analyse the laws of thermodynamics governing the behaviour of cosmological horizons in de Sitter space and their map to a holographic description at future infinity, $\mathcal{I…
extremal surfaces, replicas, boundary Renyi entropies in and time entanglement
Kanhu Kishore Nanda, K. Narayan, Somnath Porey +1
We develop further previous work on de Sitter extremal surfaces and time entanglement structures in quantum mechanics. In the first part, we first discuss explicit quotient geometr…
JT Gravity in de Sitter Space and Its Extensions
Indranil Dey, Kanhu Kishore Nanda, Akashdeep Roy +2
We discuss and extend some aspects pertaining to the canonical quantisation of JT gravity in de Sitter space, including the problem of time and the construction of a Hilbert space.…
Aspects of dS/CFT Holography
Indranil Dey, Kanhu Kishore Nanda, Akashdeep Roy +1
It has been suggested that a spacetime of radius has a holographic dual, living at future space-like infinity , with the bulk wave function being du…
Operators in the Internal Space and Locality
Hardik Bohra, Sumit R. Das, Gautam Mandal +3
Realizations of the holographic correspondence in String/M theory typically involve spacetimes of the form where is some internal space which geometrizes an inte…
JT Gravity in de Sitter Space and the Problem of Time
Kanhu Kishore Nanda, Sunil Kumar Sake, Sandip P. Trivedi
We discuss the canonical quantisation of JT gravity in de Sitter space, following earlier work by Henneaux, with particular attention to the problem of time. Choosing the dilaton a…
Entanglement Entropy in Internal Spaces and Ryu-Takayanagi Surfaces
Sumit R. Das, Anurag Kaushal, Gautam Mandal +3
We study minimum area surfaces associated with a region, , of an internal space. For example, for a warped product involving an asymptotically space and an internal space…
