All Order Gravitational Wave Tails for Subleading Post-Newtonian Expansion
Debanjan Karan, Babli Khatun
The low-frequency gravitational waveform emitted in a classical scattering process contains an infinite tower of late- and early-time tail terms of the form ,…
All-Orders Classical Soft Graviton Theorems in the Newtonian Limit and Beyond
Debanjan Karan, Babli Khatun, Raghu Mahajan +2
The classical soft graviton theorem aims to determine certain terms in the early- and late-time tails of the gravitational waveform produced in a scattering process, using only the…
Reconstructing cosmological correlators via dispersion: from cutting to dressing rules
Shibam Das, Debanjan Karan, Babli Khatun +1
In this work, we investigate how cosmological correlators can be reconstructed by applying the momentum-space dispersion formula to their discontinuities, treating them as function…
A single-cut discontinuity for cosmological correlators from unitarity and analyticity
Shibam Das, Debanjan Karan, Babli Khatun +1
We derive discontinuity relations, also known as cutting rules, and explore the analytic properties of cosmological correlators, fundamental observables of the primordial universe.…
All Order Classical Electromagnetic Soft Theorems
Debanjan Karan, Babli Khatun, Biswajit Sahoo +1
If a set of charged objects collide in space and the fragments disperse, then this process will emit electromagnetic waves. Classical soft photon theorem determines the constant te…
