New Asymptotic Conservation laws for Electromagnetism
Sayali Atul Bhatkar
We obtain the subleading tail to the memory term in the late time electromagnetic radiative field generated due to a generic scattering of charged bodies. We show that there exists…

Ward identity for loop level soft photon theorem for massless QED coupled to gravity
Sayali Atul Bhatkar
Strominger and his collaborators pioneered the study of equivalence between soft theorems and asymptotic conservation laws. We study this equivalence in the context of loop level s…

Subleading Soft Theorem for arbitrary number of external soft photons and gravitons
Sayali Atul Bhatkar, Biswajit Sahoo
We obtain the subleading soft theorem for a generic theory of quantum gravity, for arbitrary number of soft photons and gravitons and for arbitrary number of finite energy particle…
