The Asymptotic Structure of Gravity in Higher Even Dimensions
Chandramouli Chowdhury, Ruchira Mishra, Siddharth G. Prabhu
We investigate the notion of asymptotic symmetries in classical gravity in higher even dimensions, with space-time dimensions as the prototype. Unlike in four dimensions, c…
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…
The Holographic Nature of Null Infinity
Alok Laddha, Siddharth G. Prabhu, Suvrat Raju +1
We argue that, in a theory of quantum gravity in a four dimensional asymptotically flat spacetime, all information about massless excitations can be obtained from an infinitesimal…
Gravitational radiation from the classical spinning double copy
Jingping Li, Siddharth G. Prabhu
We establish a correspondence between perturbative classical gluon and gravitational radiation emitted by spinning sources, to linear order in spin. This is an extension of the non…
Classical gluon and graviton radiation from the bi-adjoint scalar double copy
Walter D. Goldberger, Siddharth G. Prabhu, Jedidiah O. Thompson
We find double copy relations between classical radiating solutions in Yang-Mills theory coupled to dynamical color charges and their counterparts in a cubic bi-adjoint scalar fiel…
