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 ...

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.

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.

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.

The Entropy Density Behavior across a Plane Shock Wave

open access: yesEntropy, 2023
Entropy density behavior poses many problems when we study non-equilibrium situations. In particular, the local equilibrium hypothesis (LEH) has played a very important role and is taken for granted in non-equilibrium problems, no matter how extreme they

Entanglement entropy from non-equilibrium Monte Carlo simulations

open access: yesJournal of High Energy Physics, 2023
We study the entanglement entropy in lattice field theory using a simulation algorithm based on Jarzynski’s theorem. We focus on the entropic c-function for the Ising model in two and in three dimensions: after validating our algorithm against known ...

Entropy Production and Irreversible Processes -from the perspective of continuous topological evolution.

open access: yesEntropy, 2004
: A concept of entropy production associated with continuous topological evolution is deduced (without statistics) from the fact that Cartan-Hilbert 1-form of Action defines a non-equilibrium symplectic system of Pfaff Topological dimension 2n+2.

ATP-Dependent Diffusion Entropy and Homogeneity in Living Cells

open access: yesEntropy, 2019
Intracellular dynamics is highly complex, and includes diffusion of poly-dispersed objects in a non-homogeneous, out-of-equilibrium medium. Assuming non-equilibrium steady-state, we developed a framework that relates non-equilibrium fluctuations to ...

Informational analysis of genetic equilibrium on different mating varieties

open access: yes浙江大学学报. 农业与生命科学版, 2006
It was demonstrated that two kinds of frequency distribution on gamete and genotype were equivalent to Hardy-Weinberg equilibrium distribution with respect to limited loci in a diploid population when the gamete entropy and genotype entropy reached ...
