BMS-supertranslation charges at the critical sets of null infinity

Mariem Magdy, Kartik Prabhu, Juan A. Valiente Kroon

For asymptotically flat spacetimes, a conjecture by Strominger states that asymptotic BMS-supertranslations and their associated charges at past null infinity can…

Supergravity model of the Haldane-Rezayi fractional quantum Hall state

Dung Xuan Nguyen, Kartik Prabhu, Ajit C. Balram +1

Supersymmetry and supergravity were invented in the 1970s to solve fundamental problems in high-energy physics. Even though neither of these ideas has yet been confirmed in high-en…

Infrared Finite Scattering Theory in Quantum Field Theory and Quantum Gravity

Kartik Prabhu, Gautam Satishchandran, Robert M. Wald

Infrared (IR) divergences arise in scattering theory with massless fields and are manifestations of the memory effect. There is nothing singular about states with memory, but they…

A novel supersymmetric extension of BMS symmetries at null infinity

Kartik Prabhu

We show that we can combine the (complex, self-dual) BMS vector fields with the recently defined BMS twistors to obtain a new supersymmetric extension of the BMS symmetries at null…

A twistorial description of BMS symmetries at null infinity

Kartik Prabhu

We describe a novel twistorial construction of the asymptotic BMS symmetries at null infinity for asymptotically flat spacetimes. We define BMS twistors as spinor solutions to some…

Conservation of asymptotic charges from past to future null infinity: Lorentz charges in general relativity

Kartik Prabhu, Ibrahim Shehzad

We show that the asymptotic charges associated with Lorentz symmetries on past and future null infinity match in the limit to spatial infinity in a class of asymptotically-flat spa…
