Hairy Black Holes, Horizon Mass and Solitons
Abhay Ashtekar, Alejandro Corichi, Daniel Sudarsky
Properties of the horizon mass of hairy black holes are discussed with emphasis on certain subtle and initially unexpected features. A key property suggests that hairy black holes…
Generic Isolated Horizons and their Applications
Abhay Ashtekar, Christopher Beetle, Olaf Dreyer +4
Boundary conditions defining a generic isolated horizon are introduced. They generalize the notion available in the existing literature by allowing the horizon to have distortion a…
Quantum Geometry of Isolated Horizons and Black Hole Entropy
A. Ashtekar, J. Baez, K. Krasnov
Using the earlier developed classical Hamiltonian framework as the point of departure, we carry out a non-perturbative quantization of the sector of general relativity, coupled to…
Isolated Horizons: Hamiltonian Evolution and the First Law
Abhay Ashtekar, Stephen Fairhurst, Badri Krishnan
A framework was recently introduced to generalize black hole mechanics by replacing stationary event horizons with isolated horizons. That framework is significantly extended. The…
Large quantum gravity effects: Cylindrical waves in four dimensions
Maria E. Angulo, Guillermo A. Mena Marugan
Linearly polarized cylindrical waves in four-dimensional vacuum gravity are mathematically equivalent to rotationally symmetric gravity coupled to a Maxwell (or Klein-Gordon) field…
