Non-Equilibrium Entropy and Irreversibility in Generalized Stochastic Loewner Evolution from an Information-Theoretic Perspective [PDF]

open access: yesEntropy, 2021
In this study, we theoretically investigated a generalized stochastic Loewner evolution (SLE) driven by reversible Langevin dynamics in the context of non-equilibrium statistical mechanics.

Second Law and Non-Equilibrium Entropy of Schottky Systems—Doubts and Verification– [PDF]

open access: yesEntropy, 2018
Meixner’s historical remark in 1969 “... it can be shown that the concept of entropy in the absence of equilibrium is in fact not only questionable but that it cannot even be defined....” is investigated from today’s insight ...

Entropy Production: Its Role in Non-Equilibrium Thermodynamics [PDF]

open access: yesEntropy, 2011
It is unquestionable that the concept of entropy has played an essential role both in the physical and biological sciences. However, the entropy production, crucial to the second law, has also other features not clearly conceived.

Entropy Principle and Recent Results in Non-Equilibrium Theories [PDF]

open access: yesEntropy, 2014
We present the state of the art on the modern mathematical methods of exploiting the entropy principle in thermomechanics of continuous media. A survey of recent results and conceptual discussions of this topic in some well-known non-equilibrium theories

A Novel Derivation of the Time Evolution of the Entropy for Macroscopic Systems in Thermal Non-Equilibrium

open access: yesEntropy, 2017
The paper discusses how the two thermodynamic properties, energy (U) and exergy (E), can be used to solve the problem of quantifying the entropy of non-equilibrium systems.

A Perspective on Lindblad’s Non-Equilibrium Entropy

open access: yesOpen Systems & Information Dynamics, 2023
In 1983 Göran Lindblad published a monograph on nonequilibrium thermodynamics. We here summarize the contents of this book, and provide a perspective on its relation to later developments in statistical physics and quantum physics. We high-light two aspects. The first is the idea that while all unitaries can be allowed in principle, different theories

Classical and Quantum H-Theorem Revisited: Variational Entropy and Relaxation Processes

open access: yesEntropy, 2021
We propose a novel framework to describe the time-evolution of dilute classical and quantum gases, initially out of equilibrium and with spatial inhomogeneities, towards equilibrium.
