Comment on an information theoretic approach to the study of non-equilibrium steady states

الأصل · EN

We argue that there is a fundamental problem regarding the analysis that serves as the foundation for the papers Information theory explanation of the fluctuation theorem, maximum entropy production and self-organized criticality in non-equilibrium stationary states [R. Dewar, J. Phys. A: Math. Gen. 36 (2003), 631-641] and Maximum entropy production and the fluctuation theorem [R. Dewar, J. Phys. A: Math. Gen. 38 (2005), L371-L381]. In particular, we demonstrate that this analysis is based on an assumption that is physically unrealistic and that, hence, the results obtained in those papers cannot be regarded as physically meaningful.
