Thermodynamics of dynamical black holes beyond perturbation theory
Abhay Ashtekar, Daniel E. Paraizo, Jonathan Shu
The close similarities of the three laws of black hole mechanics, discovered by Bardeen, Carter and Hawking, with the laws of thermodynamics led to the identification of a multiple…
Thermodynamics of Black Holes, far from Equilibrium
Abhay Ashtekar, Daniel E. Paraizo, Jonathan Shu
As in thermodynamics, the celebrated first law of black hole mechanics relates infinitesimal changes in the properties of nearby equilibrium states of black holes (without referenc…
Quasi-Local Black Hole Horizons: Recent Advances
Abhay Ashtekar, Badri Krishnan
While the early literature on black holes focused on event horizons, subsequently it was realized that their teleological nature makes them unsuitable for many physical application…
Dynamical Horizon Segments and Spacetime Isometries
Abhay Ashtekar, Badri Krishnan
Given a space-time admitting a dynamical horizon segment (DHS) , we show that there are stringent constraints on the Killing fields that…
Black Hole Evaporation in Loop Quantum Gravity
Abhay Ashtekar
The conference \emph{Black Holes Inside and Out} marked the 50th anniversary of Hawking's seminal paper on black hole radiance. It was clear already from Hawking's analysis that a…
