Geometrothermodynamics of the Kehagias-Sfetsos Black Hole
W. Janke, D. A. Johnston, R. Kenna
The application of information geometric ideas to statistical mechanics using a metric on the space of states, pioneered by Ruppeiner and Weinhold, has proved to be a useful altern…
The Grand-Canonical Asymmetric Exclusion Process and the One-Transit Walk
R. A. Blythe, W. Janke, D. A. Johnston +1
The one-dimensional Asymmetric Exclusion Process (ASEP) is a paradigm for nonequilibrium dynamics, in particular driven diffusive processes. It is usually considered in a canonical…
Information Geometry, One, Two, Three (and Four)
D. A. Johnston, W. Janke, R. Kenna
Although the notion of entropy lies at the core of statistical mechanics, it is not often used in statistical mechanical models to characterize phase transitions, a role more usual…
The Information Geometry of the One-Dimensional Potts Model
B. P. Dolan, D. A. Johnston, R. Kenna
In various statistical-mechanical models the introduction of a metric onto the space of parameters (e.g. the temperature variable, , and the external field variable, , in the…
