Entropy Production in Gaussian Thermostats [PDF]
Communications in Mathematical Physics, 2006 We show that an arbitrary Anosov Gaussian thermostat on a surface is dissipative unless the external field has a global potential.

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.

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 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.

Entropy production in random billiards
Discrete & Continuous Dynamical Systems - A, 2021 We introduce a class of random mechanical systems called random billiards to study the problem of quantifying the irreversibility of nonequilibrium macroscopic systems. In a random billiard model, a point particle evolves by free motion through the interior of a spatial domain, and reflects according to a reflection operator, specified in the model by ...

Physical Review X, 2017 We study the statistics of infima, stopping times, and passage probabilities of entropy production in nonequilibrium steady states, and we show that they are universal. We consider two examples of stopping times: first-passage times of entropy production

Nonequilibrium quantum-impurities: from entropy production to information theory
, 2007 Nonequilibrium steady-state currents, unlike their equilibrium counterparts, continuously dissipate energy into their physical surroundings leading to entropy production and time-reversal symmetry breaking.

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

Bacterial chemotaxis and entropy production [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2010 Entropy production is calculated for bacterial chemotaxis in the case of a migrating band of bacteria in a capillary tube. It is found that the speed of the migrating band is a decreasing function of the starting concentration of the metabolizable attractant.

On the validity of entropy production principles for linear electrical circuits
, 2007 We discuss the validity of close-to-equilibrium entropy production principles in the context of linear electrical circuits. Both the minimum and the maximum entropy production principle are understood within dynamical fluctuation theory.
