Entropy production of resetting processes

open access: yesPhysical Review Research, 2023
Stochastic systems that undergo random restarts to their initial state have been widely investigated in recent years, both theoretically and in experiments.

An Analysis of the Characteristics of Internal Flow Losses of Seawater Circulation Pumps in Nuclear Power Plants Based on the Entropy Production Theory

open access: yesEnergies
The seawater circulation pump represents the pump product with the largest flow rate within nuclear power plants. Its energy consumption accounts for a substantial portion of the energy consumed by nuclear power plants.

Conditional Entropy Production and Quantum Fluctuation Theorem of Dissipative Information: Theory and Experiments

open access: yesPRX Quantum, 2022
We study quantum conditional entropy production, which quantifies the irreversibility of system-environment evolution from the perspective of a third system, called the reference. The reference is initially correlated with the system.

Entropy production by evapotranspiration and its geographic variation

open access: yesSoil and Water Research, 2008
The hydrologic cycle is a system far from thermodynamic equilibrium that is characterized by its rate of entropy production in the climatological mean steady state.

Free and classical entropy over the circle. [PDF]

open access: yes, 2007
Relative entropy with respect to normalized arclength measure on the circle is greater than or equal to the negative logarithmic energy (Voiculescu's negative free entropy) and is greater than or equal to the modified relative free entropy.

Entropy current and entropy production in relativistic spin hydrodynamics

open access: yesPhysics Letters B
We use a first-principle quantum-statistical method to derive the expression of the entropy production rate in relativistic spin hydrodynamics. We show that the entropy current is not uniquely defined and can be changed by means of entropy-gauge ...

Estimating time-dependent entropy production from non-equilibrium trajectories

open access: yesCommunications Physics, 2022
While methods for estimating the entropy production rate of a stationary process are relatively well established, this is still a challenge in non-stationary conditions.

On Entropic Framework Based on Standard and Fractional Phonon Boltzmann Transport Equations

open access: yesEntropy, 2019
Generalized expressions of the entropy and related concepts in non-Fourier heat conduction have attracted increasing attention in recent years. Based on standard and fractional phonon Boltzmann transport equations (BTEs), we study entropic functionals ...

Evaluation of the Atmospheric Chemical Entropy Production of Mars [PDF]

open access: yes, 2015
Thermodynamic disequilibrium is a necessary situation in a system in which complex emergent structures are created and maintained. It is known that most of the chemical disequilibrium, a particular type of thermodynamic disequilibrium, in Earth’s ...

Entropy Production in the Theory of Heat Conduction in Solids

open access: yesEntropy, 2016
The evolution of the entropy production in solids due to heat transfer is usually associated with the Prigogine’s minimum entropy production principle.
