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…
Investigation of all Ricci semi-symmetric and all conformally semi-symmetric spacetimes
Jan E. Åman
We find all Ricci semi-symmetric as well as all conformally semi-symmetric spacetimes. Neither of these properties implies the other. We verify that only conformally flat spacetime…
On explicit thermodynamic functions and extremal limits of Myers-Perry black holes
Jan E. Aman, Narit Pidokrajt
We study thermodynamic properties of Myers-Perry black holes by deriving explicit fundamental relations from which we can obtain the temperature and specific heat in terms of expli…
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…
