Large deflection scattering, soft radiation and KMOC formalism
Samim Akhtar, Alok Laddha, Arkajyoti Manna +1
KMOC (Kosower, Maybee, and O'Connell) formalism is an approach to analyze classical scattering in gauge theories and gravity using a class of ``inclusive'' observables which can be…
5-Dimensional Gravitational Raman Scattering: Scalar Wave Perturbations in Schwarzschild-Tangherlini Spacetime
Samim Akhtar, Yilber Fabian Bautista, Cristoforo Iossa +1
In this Letter, we study scalar wave perturbations of arbitrary frequency to the 5D Schwarzschild-Tangherlini black hole (STBH) within general relativity. For the first time, we de…
On the classical limit of the (sub)-leading soft graviton theorems in without deflection
Samim Akhtar
Tree-level gravitational amplitudes satisfy an infinite hierarchy of soft factorization theorems. The existence of these theorems has been recently linked with the existence of an…
Classical Observables using Exponentiated Spin factors: Electromagnetic Scattering
Samim Akhtar, Arkajyoti Manna, Akavoor Manu
In [arXiv:1906.10100], the authors argued that the Newman-Janis algorithm on the space of classical solutions in general relativity and electromagnetism could be used in the space…
Open Quantum Entanglement: A study of two atomic system in static patch of de Sitter space
Samim Akhtar, Sayantan Choudhury, Satyaki Chowdhury +3
In this work, our prime objective is to study non-locality and long-range effects of two-body correlation using quantum entanglement from the various information-theoretic measures…
