Effective field theory of stochastic diffusion from gravity
Jewel K. Ghosh, R. Loganayagam, Siddharth G. Prabhu +3
Planar black holes in AdS have long-lived quasinormal modes which capture the physics of charge and momentum diffusion in the dual field theory. How should we characterize the effe…
Comments on Sen's Classical Entropy Function for Static and Rotating AdS Black Holes
Jewel K. Ghosh, Leopoldo A. Pando Zayas
We consider various aspects of Sen's classical entropy function formalism for asymptotically AdS black holes with emphasis on its efficacy to capture higher derivative correcti…
Back-reaction in massless de Sitter QFTs: holography, gravitational DBI action and f(R) gravity
Jewel Kumar Ghosh, Elias Kiritsis, Francesco Nitti +1
We employ gauge-gravity duality to study the backreaction effect of 4-dimensional large- quantum field theories on constant-curvature backgrounds, and in particular de Sitter sp…
