Effective Field Theory of Quantum Black Holes
Sangmin Choi, Finn Larsen
We review and extend recent progress on the quantum description of near-extremal black holes in the language of effective quantum field theory. With black holes in Einstein-Maxwell…
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…
Subleading soft dressings of asymptotic states in QED and perturbative quantum gravity
Sangmin Choi, Ratindranath Akhoury
We construct Faddeev-Kulish states in QED and perturbative quantum gravity to subleading order in the soft momentum expansion and to first order in the coupling constant, using the…
Soft Photon Hair on Schwarzschild Horizon from a Wilson Line Perspective
Sangmin Choi, Ratindranath Akhoury
We develop a unified framework for the construction of soft dressings at boundaries of spacetime, such as the null infinity of Minkowski spacetime and the horizon of a Schwarzschil…
