Asymptotic Symmetries and Charges in De Sitter Space
(Institute of Physics Publishing, 2011)The asymptotic symmetry group (ASG) at future null infinity \((I^+)\) of four-dimensional de Sitter spacetimes is defined and shown to be given by the group of three-dimensional diffeomorphisms acting on \(I^+\). Finite ... -
Black Hole Superradiance From Kerr/CFT
(Springer Verlag, 2010)The superradiant scattering of a scalar field with frequency and angular momentum (w,m) by a near-extreme Kerr black hole with mass and spin (M, J) was derived in the seventies by Starobinsky, Churilov, Press and Teukolsky. ...
