On entropy production

Annals of Physics, 2008
The paper's methodology traces back to Prigogine's theory of irreversible systems and an issue of irreversible time evolution in Onsager's formulation. The super-operator technique is developed, based on earlier papers of the present Author, with the aim of reconciling the conceptual background of an irreversible dynamics with principles of standard ...

Minimum entropy production in photosynthesis

Biophysical Chemistry, 2001
In this paper a flux-coupling model of photosynthesis is presented. By requiring minimum entropy production, it is found that the photosynthetic efficiency is essentially given by the square root of D/lambda. D and lambda are the diffusion coefficient and thermal conductivity of the rate-limiting processes in the chloroplast, respectively.

Transformation properties of entropy production

Physical Review E, 2011
The transformation properties of entropy production under phase-space partitioning, lumping, or the elimination of intermediate steps and variables in the presence of widely separated time scales are studied. Conditions are derived under which dissipation remains invariant.

Entropy and Entropy Production: Discussion Paper

1973
I conceive my role to be that of a trigger for what, I hope, will turn out to be a lively discussion.

Variational Principles and Entropy Production

Physical Review, 1963
We have found a variational principle which is valid for irreversible processes, whether microscopic reversibility is obeyed or not, and beyond the region of linear response. A convenient general expression for entropy production is also found and the relation of entropy production to the solution of transport problems is discussed.

Multiplicative Entropy-Energy Product Entropy VS Statistical Entropy

Abstract:This paper introduces a novel entropy formulation — multiplicative entropy — defined as the product of energy values across all units in a closed system. Unlike traditional statistical entropy, this approach explicitly tracks irreversible energy redistribution pathways, offering an analytic and path-dependent description of entropy growth ...

Energy Product Entropy VS Statistical Entropy

Abstract:This paper introduces a novel entropy formulation — multiplicative entropy — defined as the product of energy values across all units in a quantized homogeneous invariant network. Unlike traditional statistical entropy, this approach explicitly tracks irreversible energy redistribution pathways, offering an analytic and path-dependent ...

Principle of Minimum Entropy Production

Physical Review, 1957
Prigogine has shown that in the steady state in which certain macroscopic affinities ${F}_{1}, {F}_{2}, \ensuremath{\cdots} {F}_{k}$ are fixed and other macroscopic affinities ${F}_{k+1}, {F}_{k+2}, \ensuremath{\cdots} {F}_{r}$ are unconstrained, the values assumed by the unconstrained affinities are such as to minimize the rate of production of ...

Radiative Entropy Production—Heat Lost to Entropy

1991
Publisher Summary This chapter deals with entropy production resulting from temperature differences. This thermal conduction energy is the lost heat that goes into entropy production. All forms of entropy production result from dissipative processes involving mass, species, momentum, heat transfer, and electromagnetic or nuclear transport.
