Estimating entropy production rates with first-passage processes [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2022
We consider the problem of estimating the mean entropy production rate in a nonequilibrium process from the measurements of first-passage quantities associated with a single current.

Irreversible entropy production: From classical to quantum [PDF]

open access: yesReviews of Modern Physics, 2020
Entropy production is a key quantity in any finite-time thermodynamic process. It is intimately tied with the fundamental laws of thermodynamics, embodying a tool to extend thermodynamic considerations all the way to non-equilibrium processes. It is also

Characteristics of Cavitation Flow for a Regulating Valve Based on Entropy Production Theory

open access: yesEnergies, 2022
A regulating valve is a key control element in the coal liquefaction industry, whose flow field distribution is related to the entropy production. In order to make a quantitative evaluation of the energy loss in the cavitation flow and calculate the ...

Analysis of Energy Loss Characteristics of Vertical Axial Flow Pump Based on Entropy Production Method under Partial Conditions

open access: yesEntropy, 2022
The energy loss of the vertical axial flow pump device increases due to the unstable internal flow, which reduces the efficiency of the pump device and increases its energy consumption of the pump device.

Minimum entropy production, detailed balance and Wasserstein distance for continuous-time Markov processes [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2021
We investigate the problem of minimizing the entropy production for a physical process that can be described in terms of a Markov jump dynamics. We show that, without any further constraints, a given time-evolution may be realized at arbitrarily small ...

Geometric decomposition of entropy production in out-of-equilibrium systems [PDF]

open access: yesPhysical Review Research, 2021
Two qualitatively different ways of driving a physical system out of equilibrium, time-dependent and non-conservative forcing, are reflected by the decomposition of the system’s entropy production into excess and housekeeping parts.

Model-Free Measurement of Local Entropy Production and Extractable Work in Active Matter. [PDF]

open access: yesPhysical Review Letters, 2021
Time-reversal symmetry breaking and entropy production are universal features of nonequilibrium phenomena. Despite its importance in the physics of active and living systems, the entropy production of systems with many degrees of freedom has remained of ...

A Photon Force and Flow for Dissipative Structuring: Application to Pigments, Plants and Ecosystems

open access: yesEntropy, 2022
Through a modern derivation of Planck’s formula for the entropy of an arbitrary beam of photons, we derive a general expression for entropy production due to the irreversible process of the absorption of an arbitrary incident photon spectrum in material ...

The Role of Vegetation on the Ecosystem Radiative Entropy Budget and Trends Along Ecological Succession

open access: yesEntropy, 2014
Ecosystem entropy production is predicted to increase along ecological succession and approach a state of maximum entropy production, but few studies have bridged the gap between theory and data.
