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…
A Brief Note on Complex AdS-Schwarzschild Black Holes
Raghu Mahajan, Kaustubh Singhi
In the context of thermodynamics of asymptotically anti-de Sitter spaces, it is often stated that at very low temperatures, there is only one saddle point available-namely, thermal…
Lectures on Quantum Extremal Surfaces and the Page Curve
Raghu Mahajan
This article is a write-up of pedagogical lectures delivered at the Asia Pacific Center for Theoretical Physics online winter school held in January 2021, and also as part of the Q…
Giant graviton expansion from eigenvalue instantons
Yiming Chen, Raghu Mahajan, Haifeng Tang
Recently, S. Murthy has proposed a convergent expansion of free partition functions and superconformal indices of finite- purely adjoint gauge theories based on a Fredholm deter…
Normalization of ZZ instanton amplitudes in type 0B minimal superstring theory
Vivek Chakrabhavi, Dan Stefan Eniceicu, Raghu Mahajan +1
We study ZZ instanton corrections in the minimal superstring theory with the type 0B GSO projection, which becomes the type 0B super-JT gravity in the $k \to \…
Instantons in sine-Liouville theory
Sergei Alexandrov, Raghu Mahajan, Ashoke Sen
We compute instanton corrections to the partition function of sine-Liouville (SL) theory, which provides a worldsheet description of two-dimensional string theory in a non-trivial…
