Thermodynamic Geometry and Type 0A Black Holes
Narit Pidokrajt, John Ward
In this note we study thermodynamic geometry of the type 0A black hole solution in string theory using a variety of different methods (Ruppeiner, Weinhold and Geometrothermodynamic…
Gauge field back-reaction in Born Infeld cosmologies
Paulo Vargas Moniz, John Ward
In this paper, we investigate the back-reaction of gauge fields into a class of inflationary settings. To be more precise, we employ a Bianchi-I geometry (taken as an anisot…
An alternative approach to tachyon cosmology
John Ward
In this note we propose the use of an alternate action for the open string tachyon on a non-BPS -brane. At the classical level this action is precisely equivalent to the more c…
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…
Type I singularities and the Phantom Menace
Tapan Naskar, John Ward
We consider the future dynamics of a transient phantom dominated phase of the universe in LQC and in the RS braneworld, which both have a non-standard Friedmann equation. We find t…
Ruppeiner theory of black hole thermodynamics
Jan E Aman, James Bedford, Daniel Grumiller +2
The Ruppeiner metric as determined by the Hessian of the Gibbs surface provides a geometric description of thermodynamic systems in equilibrium. An interesting example is a black h…
