Metallic transports from accelerating black holes
Dibakar Roychowdhury
We probe four dimensional accelerating black holes with D-brane and build up the notion of metallic holography for spacetime with negative cosmological constant. We explore various…
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…
Holographic zero sound for SCFTs in 4d
Dibakar Roychowdhury
We build up the notion of metallic holography for SCFTs in four dimensions, in the presence of a finite chemical potential. We compute two point correlation…
Factorised scattering and (non)integrability for marginally deformed
Dibakar Roychowdhury
We study non-SUSY CFTs that are marginal deformations of SCFTs in 4d. We explore the fate of integrability and/or non-integrability in these CFTs using the techni…
Magnons and spikes for linear quivers and their non-Abelian T-duals
Dibakar Roychowdhury
We compute the spectra associated with various semiclassical string states that propagate over Gaiotto-Maldacena backgrounds. As an interesting special case, for th…
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…
