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…

Temperature and Moduli Independence of the Supersymmetric Index from Gravity
Raghu Mahajan, Ashoke Sen
The supersymmetric index, which gives a signed count of the microstates of black holes, can be computed directly from a gravitational path integral with appropriate boundary condit…

Instanton-Induced Closed-String Amplitudes in Minimal Superstring Theory at Subleading Order
Jyotirmoy Barman, Rishabh Kaushik, Raghu Mahajan +2
We compute the disk one-point function, the disk two-point function, and the annulus one-point function of the cosmological constant operator in the type 0A and type 0B minimal sup…
