# Is equilibrium always an entropy maximum?

@article{Landsberg1984IsEA, title={Is equilibrium always an entropy maximum?}, author={Peter Landsberg}, journal={Journal of Statistical Physics}, year={1984}, volume={35}, pages={159-169} }

A systematic development is given of the view that in the case of systems with long-range forces and which are therefore nonextensive (in some sense) some thermodynamic results do not hold. Among these is the relationU − TS + pΝ = ΜN and the Gibbs-Duhem equation. If a search for an equilibrium state is made by maximization of the entropy one may obtain misleading results because superadditivity may be violated. The considerations are worked out for a simple gas model, but they are relevant to…

Problems of nonextensivity in hadron thermodynamics

- Physics
- 1987

Hadron thermodynamics deals with a gas of indistinguishable particles whose mass spectrum is taken to have the formKmaebm. A long-standing inconsistency is pointed out, namely the nonextensive nature…

Entropy, Order and Disorder

- Physics

Entropy is one of the few physical properties of a system that cannot be measured directly, but must be deduced or calculated from other properties. It is also a property that has been defined in a…

Thermodynamic Classifications and Dilatonic Black Holes

- Mathematics
- 1997

We analyze the thermodynamics of systems which have entropy functions of the type S(m) = amβ + b, where m is an extensive variable and a, b, and β are constants. Such functions apply to dilatonic…

Boltzmann Entropy: Generalization and Applications

- Computer ScienceJournal of biological physics
- 1997

The object of the paper is to generalize Boltzmann entropy to take account of the subjective nature of a system and apply it to an ecological system leading to some interesting new results in violation of existing physical laws.

Entropy and the Unity of Knowledge II

- Environmental Science
- 1987

The boundary between thermodynamics and astrophysics is considered by tracing some consequences of the fact that the black hole entropy is not extensive. It is inferred that there are eight…

Quasi-homogeneous thermodynamics and black holes

- Physics
- 2003

We propose a generalized thermodynamics in which quasi-homogeneity of the thermodynamic potentials plays a fundamental role. This thermodynamic formalism arises from a generalization of the approach…

I. Nonextensive Statistical Mechanics and Thermodynamics: Historical Background and Present Status

- Physics
- 2001

The domain of validity of standard thermodynamics and Boltzmann-Gibbs statistical mechanics is focused on along a historical perspective. It is then formally enlarged in order to hopefully cover a…

Recent advances in axiomatic treatments of thermodynamics are surveyed, by considering the new ideas rather than the mathematical technicalities. It is shown that the advance has been considerable,…
