Superrotations are Linkages
Ratindranath Akhoury, Arielle Schutz, David Garfinkle
We show that superrotations can be described using the geometric conformal completion method of Penrose. In particular, superrotation charges can be described and calculated using…
Singular Supertranslations and Chern-Simons Theory on the Black Hole Horizon
Ratindranath Akhoury, Sangmin Choi, Malcolm J. Perry
We construct the standard and dual supertranslation charges on the future horizon of the Schwarzschild black hole, using the first-order formulation of gravity with the Holst actio…
Holography from Singular Supertranslations on a Black Hole Horizon
Ratindranath Akhoury, Sangmin Choi, Malcolm J. Perry
We investigate the standard and dual Bondi-Metzner-Sachs (BMS) supertranslation generators on a black hole horizon and draw some conclusions about black hole physics. Recently, it…
Entanglement, Renormalization and Effective Field Theories
Bingzheng Han, Ratindranath Akhoury
We develop the idea that renormalization, decoupling of heavy particle effects from low energy physics and the construction of effective field theories are intimately linked to the…
Magnetic Soft Charges, Dual Supertranslations and 't Hooft Line Dressings
Sangmin Choi, Ratindranath Akhoury
We construct the Faddeev-Kulish asymptotic states in a quantum field theory of electric and magnetic charges. We find that there are two kind of dressings: apart from the well know…
Supertranslation Hair of Schwarzschild Black Hole: A Wilson Line Perspective
Sangmin Choi, S. Sandeep Pradhan, Ratindranath Akhoury
We demonstrate within the quantum field theoretical framework that an asymptotic particle falling into the black hole implants soft graviton hair on the horizon, conforming with th…
