Thermodynamics and an Introduction to Thermostatistics
TL;DR: The Canonical Formalism Statistical Mechanics in the Entropy Representation as mentioned in this paper is a generalization of statistical mechanics in the Helmholtz Representation, and it has been applied to general systems.
Journal ArticleDOI
Irreversibility and Generalized Noise
TL;DR: In this article, a relation between the generalized resistance and the generalized forces in linear dissipative systems is obtained, which forms the extension of the Nyquist relation for the voltage fluctuations in electrical impedances.
Journal ArticleDOI
The present status of the temperature dependence of magnetocrystalline anisotropy, and the l(l+1)2 power law
Herbert B. Callen,Earl Callen +1 more
TL;DR: The present status of the theory of the temperature dependence of magnetocrystalline anisotropy in ferromagnetic insulators is reviewed and summarized in this paper, where the l(l+1) 2 power law for the behavior at low temperatures is derived in a general fashion and the extension to arbitrary temperatures is also given.
Journal ArticleDOI
On a Theorem of Irreversible Thermodynamics
TL;DR: In this paper, a relation between the parameter describing the irreversible response of a driven dissipative system and the spontaneous fluctuations of the thermodynamic extensive parameters of the system in equilibrium is obtained.
Journal ArticleDOI
Green function theory of ferromagnetism
TL;DR: A theory of ferromagnetism for general spin, approximately valid through the entire temperature range, is given in this paper, where the Green function is decoupled by a physical criterion involving self-consistency of the decoupling at all temperatures.
