Revisiting Logarithmic Correction to Five Dimensional BPS Black Hole Entropy
A. H. Anupam, Chandramouli Chowdhury, Ashoke Sen
We compute logarithmic correction to five dimensional BPS black hole entropy using finite temperature black hole geometry and find perfect agreement with the microscopic results an…
Logarithmic Correction to BPS Black Hole Entropy from Supersymmetric Index at Finite Temperature
Anupam A. H., P. V. Athira, Chandramouli Chowdhury +1
It has been argued by Iliesiu, Kologlu and Turiaci in arXiv:2107.09062 that one can compute the supersymmetric index of black holes using black hole geometry carrying finite temper…
Analytic Results for Loop-Level Momentum Space Witten Diagrams
Chandramouli Chowdhury, Kajal Singh
This paper presents an evaluation of the wave function coefficients for conformally coupled scalars at both one and two-loop levels at leading order in the coupling constant, in mo…
Generalized BMS algebra in higher even dimensions
Chandramouli Chowdhury, Anupam A. H., Arpan Kundu
We revisit the status of asymptotic symmetries in higher even dimensions and propose a definition of superrotation charge beyond linearized gravity. We prove that there is a well-d…
Recovering information in an asymptotically flat spacetime in quantum gravity
Chandramouli Chowdhury, Olga Papadoulaki
As an extension of arXiv:\{2002.02448, 2008.10740\} we present a physical protocol that a set of observers can use to detect a pure state in the bulk when they are spread across a…
The Asymptotic Structure of Gravity in Higher Even Dimensions
Chandramouli Chowdhury, Ruchira Mishra, Siddharth G. Prabhu
We investigate the notion of asymptotic symmetries in classical gravity in higher even dimensions, with space-time dimensions as the prototype. Unlike in four dimensions, c…
Holography from the Wheeler-DeWitt equation
Chandramouli Chowdhury, Victor Godet, Olga Papadoulaki +1
In a theory of quantum gravity, states can be represented as wavefunctionals that assign an amplitude to a given configuration of matter fields and the metric on a spatial slice. T…
Irreversibility, heat and information flows induced by non-reciprocal interactions
Sarah A. M. Loos, Sabine H. L. Klapp
We study the thermodynamic properties induced by non-reciprocal interactions between stochastic degrees of freedom in time- and space-continuous systems. We show that, under fairly…
On loop celestial amplitudes for gauge theory and gravity
Soner Albayrak, Chandramouli Chowdhury, Savan Kharel
Scattering amplitudes of massless particles in Minkowski space can be expressed in a conformal basis by Mellin transforming the momentum space amplitudes to correlation functions o…
An étude of momentum space scalar amplitudes in AdS
Soner Albayrak, Chandramouli Chowdhury, Savan Kharel
In this paper, we explore momentum space approach to computing scalar amplitudes in Anti-de Sitter space. We show that the algorithm derived by Arkani-Hamed, Benincasa, and Postnik…
New relation for AdS amplitudes
Soner Albayrak, Chandramouli Chowdhury, Savan Kharel
In this paper, we present a simple and iterative algorithm that computes Anti-de Sitter space scattering amplitudes. We focus on the vector correlators in AdS in four dimensions in…
How robust is the indistinguishability between quantum fluctuation seen from non-inertial frame and real thermal bath
Chandramouli Chowdhury, Susmita Das, Surojit Dalui +1
We re-advocated the conjecture of indistinguishability between the quantum fluctuation observed from a Rindler frame and a real thermal bath, for the case of a free massless scalar…
Conformal Vacuum and Fluctuation-Dissipation in de-Sitter Universe and Black Hole Spacetimes
Ashmita Das, Surojit Dalui, Chandramouli Chowdhury +1
In the studies of quantum field theory in curved spacetime, the ambiguous concept of vacuum state and the particle content is a long-standing debatable aspect. So far it is well kn…
Friedel oscillations and dynamical density of states of an inhomogeneous Luttinger liquid
Joy Prakash Das, Chandramouli Chowdhury, Girish S. Setlur
In this work, the four-point Green functions relevant to the study of Friedel oscillations are calculated for a Luttinger liquid with a cluster of impurities around an origin using…
Non-chiral bosonization of strongly inhomogeneous Luttinger liquids
Joy Prakash Das, Chandramouli Chowdhury, Girish S. Setlur
Non-chiral bosonization (NCBT) is a non-trivial modification of the standard Fermi-Bose correspondence in one spatial dimensions made in order to facilitate the study of strongly i…
Unruh-DeWitt detector in presence of multiple scalar fields : A Toy Model
Chandramouli Chowdhury, Ashmita Das, Bibhas Ranjan Majhi
Applications of Unruh-Fulling (UF) effect are well studied in literature via the interaction of Unruh-DeWitt (UD) detector and {\it single} scalar field. In this work, we investiga…
Fluctuation-dissipation in accelerated frames
Ananya Adhikari, Krishnakanta Bhattacharya, Chandramouli Chowdhury +1
An uniformly accelerated (Rindler) observer will detect particles in the Minkowski vacuum, known as Unruh effect. The spectrum is thermal and the temperature is given by that of th…
The Quantum Steeplechase
Joy Prakash Das, Chandramouli Chowdhury, Girish S. Setlur
Quantum Steeplechase is the study of a Luttinger liquid (LL) in one dimension in the presence of a finite number of barriers and wells clustered around an origin. The powerful non-…
