Spin Multipole Expansion of the Memory Effect
Nikhil Kalyanapuram
Using two-dimensional duals of soft dynamics in QED and gravity, we perform an expansion of the respective memory effects in spin multipoles.
Holographic Representations of Supertranslation Eigenstates
Nikhil Kalyanapuram
We construct by direct computation holographic presentations of supertranslation vacua given a set of supermomenta. To do this, we make use of two-dimensional dual models recently…
Infrared and Holographic Aspects of the -Matrix in Gauge Theory and Gravity
Nikhil Kalyanapuram
Soft theorems in gauge theory and gravity encode the universal properties of scattering amplitudes as the zero frequency limit of one or more external states is approached. When th…
The Holographic Soft -Matrix in QED and Gravity
Nikhil Kalyanapuram
At leading order, the -matrices in QED and gravity are known to factorise, providing unambiguous determinations of the parts divergent due to infrared contributions. The soft $S…
On Chiral Splitting and the Ambitwistor String
Nikhil Kalyanapuram
Scattering amplitudes computed by superstring perturbation theory are known to holomorphically split into chiral half integrands at fixed internal loop momentum. It is established…
Ambitwistor Integrands from Tensionless Chiral Superstring Integrands
Nikhil Kalyanapuram
It is established that in the tensionless limit the chiral superstring integrand is reduced to the chiral integrand of the ambitwistor string.
