Generalization of Prigogine’s theorem for the case of full differential of entropy
MethodsX, 2018 In this paper we propose a solution to the problem associated with the presence of an incomplete differential of entropy in Prigogine's theorem on the minimum of entropy production.

Entropy production theorems and some consequences [PDF]
, 2009 The total entropy production fluctuations are studied in some exactly solvable models. For these systems, the detailed fluctuation theorem holds even in the transient state, provided initially the system is prepared in thermal equilibrium.

, 2021 We introduce lower bounds for the rate of entropy production of an active stochastic process by quantifying the irreversibility of stochastic traces obtained from mesoscopic degrees of freedom.

Learning entropy production via neural networks [PDF]
Physical Review Letters, 2020 This Letter presents a neural estimator for entropy production (NEEP), that estimates entropy production (EP) from trajectories of relevant variables without detailed information on the system dynamics.

Numerical investigation of entropy generation of turbulent flow in twisted tri-lobed tubes
Case Studies in Thermal Engineering, 2023 Twisted tri-lobed tubes have garnered attention due to their exceptional heat transfer efficiency and straightforward fabrication. Existing literature lacks comprehensive assessments of the overall heat transfer performance of twisted tri-lobed tubes ...

Entropy production and fluctuation theorems in a continuously monitored optical cavity at zero temperature [PDF]
Quantum, 2022 Fluctuation theorems allow one to make generalised statements about the behaviour of thermodynamic quantities in systems that are driven far from thermal equilibrium. In this article we use Crooks' fluctuation theorem to understand the entropy production

Calculation of the Entropy Balance Equation in a Non-equilibrium Reaction-diffusion System
Entropy, 2010 In this article, we discuss the relationships between thermodynamic quantities and the spatial pattern in a reaction-diffusion model based on the reversible Gray-Scott model.

Macroscopic Time-Reversal Symmetry Breaking at Nonequilibrium Phase Transition
, 2015 We study the entropy production in a macroscopic nonequilibrium system that undergoes an order-disorder phase transition. Entropy production is a characteristic feature of nonequilibrium dynamics with broken detailed balance. It is found that the entropy

Run-and-tumble motion in a harmonic potential: field theory and entropy production [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2020 Run-and-tumble (RnT) motion is an example of active motility where particles move at constant speed and change direction at random times. In this work we study RnT motion with diffusion in a harmonic potential in one dimension via a path integral ...
