Hall transports from Taub-NUT AdS black holes
Mohd Aariyan Khan, Hemant Rathi, Dibakar Roychowdhury
We compute Hall transport coefficients associated with Taub-NUT AdS black holes in four space-time dimensions using the probe D-brane approach. In particular, we examine the effect…
Probing sine dilaton gravity with flow central charge
Paramesh Mahapatra, Hemant Rathi, Dibakar Roychowdhury
We construct a holographic c-function for sine dilaton gravity (sDG) in the domain wall gauge. We show the equivalence between sDG and the two copies of Liouville conformal field t…
Metallic transports from Taub-NUT AdS black holes
Mohd Aariyan Khan, Hemant Rathi, Dibakar Roychowdhury
We compute holographic DC conductivity associated with the Taub-NUT- black holes following the probe D-brane approach. In particular, we examine the effects of frame draggin…
Holographic central charge for sine dilaton gravity
Paramesh Mahapatra, Hemant Rathi, Dibakar Roychowdhury
In this paper, we calculate the holographic central charge () associated with sine dilaton gravity (sDG) in the semiclassical limit. In the low energy limit, the sDG flows…
Topology of black hole phase transition in JT gravity
Hemant Rathi, Dibakar Roychowdhury
We present a JT gravity setup coupled with and Yang-Mills fields in two dimensions that reveals the onset of a small black hole to large black hole phase transition…
AdS_2/CFT_1 at finite density and holographic aspects of 2D black holes
Hemant Rathi
In the present thesis, we study various models of 2D dilaton gravity known as JT gravity coupled with non-trivial gauge interactions (for instance Yang-Mills, quartic inter…
Carrollian expansion of Born-Infeld Electrodynamics
Aditya Mehra, Hemant Rathi, Dibakar Roychowdhury
In this paper, we carry out a detailed investigation of Born-Infeld Electrodynamics in the Carrollian limit. We explore these theories by looking at expansion in a small c limit at…
Yang-Baxter deformed wedge holography
Gopal Yadav, Hemant Rathi
In this paper, we construct the wedge holography in the presence of homogeneous Yang-Baxter deformation. We observe that the DGP term is the reason for the existence of non-zero te…
holography and ModMax
Hemant Rathi, Dibakar Roychowdhury
We present a JT gravity set up in the presence of projected ModMax corrections in two dimensions. Our starting point is the Einstein's gravity in four dimensions accompanied by the…
Non-chaotic dynamics for Yang-Baxter deformed superstrings
Jitendra Pal, Hemant Rathi, Arindam Lala +1
We explore a novel class of Yang-Baxter deformed AdS CP backgrounds [Jour. High Ener. Phys. \textbf{01} (2021) 056] which exhibit a non-chaotic dynamics for (s…
Phases of Euclidean wormholes in JT gravity
Hemant Rathi, Dibakar Roychowdhury
We present a JT gravity set up that reveals the evidence of (Euclidean) wormhole to black hole phase transition at finite charge density and/or chemical potential. We identify the…
Holographic JT gravity with quartic couplings
Hemant Rathi, Dibakar Roychowdhury
We construct the most general theory of 2D Einstein-dilaton gravity coupled with gauge fields that contains all the 2-derivative and the 4-derivative interactions allowed by…
JT gravity and the models of Hawking-Page transition for 2D black holes
Arindam Lala, Hemant Rathi, Dibakar Roychowdhury
We propose a top down construction for Jackiw-Teitelboim (JT) gravity using compactification of gravity theories in the presence of Abelian () as well as …
