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…
Symmetry Constraints in Inflation, -vacua, and the Three Point Function
Ashish Shukla, Sandip P. Trivedi, V. Vishal
The Ward identities for conformal symmetries in single field models of inflation are studied in more detail in momentum space. For a class of generalized single field models, where…
