Hironaka Geometry and Resurgence in Finite- Matrix Models
Robert de Mello Koch, Vinayak Raj, Anik Rudra
We study how finite- invariant theory organizes the non-perturbative structure of matrix models. For a model of four traceless Hermitian matrices, the Hironaka decom…
A pedagogical introduction to invariant theory and finite- holography
Robert de Mello Koch, Minkyoo Kim, Augustine Larweh Mahu +1
These lectures provide a pedagogical introduction to the study of finite- physics of the AdS/CFT correspondence. More specifically we develop the consequences of the trace relat…
Overcrowding and the Finite- Hilbert Space
Robert de Mello Koch, Anik Rudra, Augustine Larweh Mahu
Finite- trace relations reorganize the Hilbert space of gauge-invariant operators beyond the freely generated large- description. We study this structure using the Hironaka d…
Bulk Reconstruction in Bilocal Holography
Robert de Mello Koch, Animik Ghosh, Minkyoo Kim +1
Bilocal holography provides a constructive approach to the higher-spin gravity theories dual to vector-model conformal field theories. Its central advantage is that it is completel…
Consistent Truncations from Duality Symmetries and Desingularization of Orbifold Uplifts
Anik Rudra, Colin Sterckx, Mario Trigiante
This paper is an extension of the results presented in \cite{Guarino:2024gke}. We study -invariant subsectors of maximal gauged supergravities and show that such models can p…
Collective Theory at Finite-: Reduction of the Emergent Hilbert Space
Robert de Mello Koch, Antal Jevicki, Garreth Kemp +1
Continuing the formulation of finite Hilbert spaces in emergent theories we study in this work symmetric collective models. For the case of bosons in dimensions…
QNMs of charged black holes in AdS spacetime: a geometrical optics perspective
Shubham Kala, Anik Rudra, Hemwati Nandan
We investigate the quasinormal modes of the ReissnerNordström antide Sitter black hole using the Penrose limit, motivated by the geometrical optics approximation. This approa…
Blackening S-folds
Adolfo Guarino, Anik Rudra, Colin Sterckx +1
We construct the universal AdS black hole that asymptotes to the -family of type IIB S-fold backgrounds dual to the conformal manifold of S-fold CFT's.…
Energy extraction and particle acceleration around a rotating dyonic black hole in , gauged supergravity
Anik Rudra, Hemwati Nandan, Radouane Gannouji +2
In the present paper, we explore various gravitational aspects such as energy extraction (via the Penrose process and Superradiance), particle collisions around a ,…
Analytic solutions of the geodesic equation for Reissner-Nordström-(anti-)de Sitter black holes surrounded by different kinds of regular and exotic matter fields
Arindam Kumar Chatterjee, Kai Flathmann, Hemwati Nandan +1
The purpose of this study is the derivation of the equation of motion for particles and light in the spacetime of Reissner-Nordström-(anti-)de Sitter black holes in the background…
A sincere tribute to E.C.G Sudarshan's phenomenal contribution toward quantum theory of optical coherence
Arindam Kumar Chatterjee, Anik Rudra, Soham Chakraborty
The diagonal representation and optical equivalence theorem are the E. C. G. Sudarshan's mid 20th century adventures in non-classical optics. It basically deals with a quantum mech…
Persistence of quantum violation of macrorealism for large spins even under coarsening of measurement times
Sumit Mukherjee, Anik Rudra, Debarshi Das +2
We investigate quantum violation of macrorealism for multilevel spin systems under the condition of coarsening of measurement times -- i.e., when measurement times have experimenta…
