A deformed IR: a new IR fixed point for four-dimensional holographic theories
Gary T. Horowitz, Maciej Kolanowski, Jorge E. Santos
In holography, the IR behavior of a quantum system at nonzero density is described by the near horizon geometry of an extremal charged black hole. It is commonly believed that for…
Almost all extremal black holes in AdS are singular
Gary T. Horowitz, Maciej Kolanowski, Jorge E. Santos
We investigate the geometry near the horizon of a generic, four-dimensional extremal black hole. When the cosmological constant is negative, we show that (in almost all cases) tida…
Symmetries of the asymptotically de Sitter spacetimes
Wojciech Kamiński, Maciej Kolanowski, Jerzy Lewandowski
We start a systematic investigation of possible isometries of the asymptotically de Sitter solutions to Einstein equations. We reformulate the Killing equation as conformal equatio…
Charges and Fluxes on (Perturbed) Non-expanding Horizons
Abhay Ashtekar, Neev Khera, Maciej Kolanowski +1
In a companion paper we showed that the symmetry group of non-expanding horizons (NEHs) is a 1-dimensional extension of the Bondi-Metzner-Sachs group …
