Squinting at massive fields from infinity
Alok Laddha, Siddharth G. Prabhu, Suvrat Raju +1
We study a novel asymptotic limit of massive scalar fields in nongravitational quantum field theories in four-dimensional flat space. We foliate the spacetime into a set of dS…
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 classical double copy in curved spacetimes: Perturbative Yang-Mills from the bi-adjoint scalar
Siddharth G. Prabhu
We formulate a version of the double copy for classical fields in curved spacetimes. We provide a correspondence between perturbative solutions to the bi-adjoint scalar equations a…
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…
Spinning particles, axion radiation, and the classical double copy
Walter D. Goldberger, Jingping Li, Siddharth G. Prabhu
We extend the perturbative double copy between radiating classical sources in gauge theory and gravity to the case of spinning particles. We construct, to linear order in spins, pe…
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…
OPE convergence in non-relativistic conformal field theories
Walter D. Goldberger, Zuhair U. Khandker, Siddharth Prabhu
Motivated by applications to the study of ultracold atomic gases near the unitarity limit, we investigate the structure of the operator product expansion (OPE) in non-relativistic…
Simultaneous B and L Violation: New Signatures from RPV-SUSY
Cyrus Faroughy, Siddharth Prabhu, Bob Zheng
Studies of R-parity violating (RPV) supersymmetry typically assume that nucleon stability is protected by approximate baryon number (B) or lepton number (L) conservation. We presen…
