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…
Jackiw-Teitelboim Model Coupled to Conformal Matter in the Semi-Classical Limit
Upamanyu Moitra, Sunil Kumar Sake, Sandip P. Trivedi +1
We analyse the Jackiw-Teitelboim model of 2D gravity coupled to massless free scalar fields in the semi-classical limit. Two systems are studied which essentially differ in the…
Jackiw-Teitelboim Gravity and Rotating Black Holes
Upamanyu Moitra, Sunil Kumar Sake, Sandip P. Trivedi +1
We show that the free energy at low temperatures for near-extremal black holes is correctly obtained from the Jackiw-Teitelboim (JT) model of gravity. Our arguments apply to all bl…
Extremal and Near-Extremal Black Holes and Near-
Upamanyu Moitra, Sandip P. Trivedi, V. Vishal
We study the behaviour of extremal and near-extremal black holes at low energies and low temperatures and find that it can be understood from the near-horizon region. Our a…
On the Dynamics of Near-Extremal Black Holes
Pranjal Nayak, Ashish Shukla, Ronak M Soni +2
We analyse the dynamics of near-extremal Reissner-Nordström black holes in asymptotically four-dimensional Anti-de Sitter space (AdS). We work in the spherically symmetric appr…
