Information geometry and phase transitions

TLDR
In this paper, the information geometry for a number of solvable statistical-mechanical models has been studied and the scalar curvature of a non-interacting model has a flat geometry (R = 0) while R diverges at the critical point of an interacting one.
Abstract
The introduction of a metric onto the space of parameters in models in statistical mechanics and beyond gives an alternative perspective on their phase structure. In such a geometrisation, the scalar curvature, R , plays a central role. A non-interacting model has a flat geometry ( R =0) , while R diverges at the critical point of an interacting one. Here, the information geometry is studied for a number of solvable statistical–mechanical models.

Geometrothermodynamics of black holes

TL;DR: In this article, the authors reformulated the thermodynamics of black holes in the context of geometrothermodynamics and showed that they are invariant with respect to Legendre transformations.

Relating Fisher information to order parameters.

TL;DR: The framework presented here reveals the basic thermodynamic reasons behind similar empirical observations reported previously and highlights the generality of Fisher information as a measure that can be applied to a broad range of systems, particularly those where the determination of order parameters is cumbersome.

P–V criticality and geometrical thermodynamics of black holes with Born–Infeld type nonlinear electrodynamics

TL;DR: In this paper, the authors take into account the black-hole solutions of Einstein gravity in the presence of logarithmic and exponential forms of nonlinear electrodynamics and study the critical behavior of the system in the context of heat capacity.

$P-V$ criticality and geometrothermodynamics of black holes with Born-Infeld type nonlinear electrodynamics

TL;DR: In this paper, the authors consider the nonlinearity effects of nonlinear electrodynamics and see how the power of non-linearity affects critical behavior, and investigate the effects of dimensionality on critical values and analyze its crucial role.

TL;DR: In this paper, the generalized Gibbs statistical states generated by a set of classical observables are considered and a concave hypersurface embedded in a linear space is shown to be a differential manifold with map given by statistical temperatures.

Information geometry of the ising model on planar random graphs.

TL;DR: The solution in field of the Ising model is used on an ensemble of planar random graphs to evaluate the scaling behavior of the scalar curvature, and a plausible scaling relation is postulated: R approximately |beta-beta(c)|(alpha-2).
