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…
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…
