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…
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…
Gravitational Wave Tails from Soft Theorem: A Short Review
Ashoke Sen
If a set of massive objects collide in space and the fragments disperse, possibly forming black holes, then this process will emit gravitational waves. Computing the detailed gravi…
Proof of the Classical Soft Graviton Theorem in D=4
Arnab Priya Saha, Biswajit Sahoo, Ashoke Sen
Classical subleading soft graviton theorem in four space-time dimensions determines the gravitational wave-form at late and early retarded time, generated during a scattering or ex…
Ultraviolet and Infrared Divergences in Superstring Theory
Ashoke Sen
Superstring theory is known to be free from ultraviolet divergences but suffers from the usual infrared divergences that occur in quantum field theories. After briefly reviewing th…
A Note on Marginally Stable Bound States in Type II String Theory
Ashoke Sen
Spectrum of elementary string states in type II string theory contains ultra-short multiplets that are marginally stable. -duality transformation converts these states into boun…
