Thermodynamic Metrics and Black Hole Physics
Jan Åman, Ingemar Bengtsson, Narit Pidokrajt
We give a brief survey of thermodynamic metrics, in particular the Hessian of the entropy function, and how they apply to black hole thermodynamics. We then provide a detailed disc…
What are extremal Kerr Killing vectors up to?
Jan E. Aman, Ingemar Bengtsson, Helgi F. Runarsson
In the extremal Kerr spacetime the horizon Killing vector field is null on a timelike hypersurface crossing the horizon at a fixed latitude, and spacelike on both sides of the hori…
Trapped surfaces
José M. M. Senovilla
I review the definition and types of (closed) trapped surfaces. Surprising global properties are shown, such as their "clairvoyance" and the possibility that they enter into flat p…
Critical phenomena and information geometry in black hole physics
Jan E. Aman, Narit Pidokrajt
We discuss the use of information geometry in black hole physics and present the outcomes. The type of information geometry we utilize in this approach is the thermodynamic (Ruppei…
Where are the trapped surfaces?
Jan E. Aman, Ingemar Bengtsson, José M. M. Senovilla
We discuss the boundary of the spacetime region through each point of which a trapped surface passes, first in some simple soluble examples, and then in the self-similar Vaidya sol…
Information geometry of asymptotically AdS black holes
Jan E. Aman, Narit Pidokrajt, John Ward
We investigate thermodynamic geometries of two families of asymptotically Anti-de Sitter black holes, i.e. the Reissner-Nordström Anti-de Sitter in four dimensions and the BTZ blac…
