# Entropy production with multiple coupling: unraveling the role of time-scales and detailed balance in biological systems

@article{Busiello2020EntropyPW, title={Entropy production with multiple coupling: unraveling the role of time-scales and detailed balance in biological systems}, author={Daniel Maria Busiello and Deepak Gupta and Amos Maritan}, journal={arXiv: Statistical Mechanics}, year={2020} }

A general framework to describe a vast majority of biological systems is to model them as stochastic processes in which multiple couplings are in play at the same time. Molecular motors, chemical reaction networks, catalytic enzymes, and particles exchanging heat with different baths, constitute some interesting examples of such a modelization. Moreover, they usually operate out of equilibrium, being characterized by a net production of entropy, which entails a constrained efficiency. Hitherto… Expand

Entropy production in systems with unidirectional transitions

- Mathematics, Physics

Efficiency and, in particular, efficiency at maximum power can be discussed systematically beyond the linear response regime for two classes of molecular machines, isothermal ones such as molecular motors, and heat engines such as thermoelectric devices, using a common framework based on a cycle decomposition of entropy production.

Systems operating out of equilibrium exchange energy and matter with the environment, thus producing entropy in their surroundings. Since the entropy production depends on the current flowing… Expand

Quantifying dissipation using fluctuating currents

- Medicine, Physics

The determination of entropy production from experimental data is a challenge but a recently introduced theoretical tool, the thermodynamic uncertainty relation, allows one to infer a lower bound on entropy production, and a critical assessment of the practical implementation is provided. Expand

Dissipation-driven selection in non-equilibrium chemical networks

A stochastic approach to nonequilibrium thermodynamics based on the expression of the entropy production rate advanced by Schnakenberg for systems described by a master equation is presented, finding a singularity at the critical point of the linear-logarithm type. Expand

Similarities and differences between non-equilibrium steady states and time-periodic driving in diffusive systems

A system that violates detailed balance evolves asymptotically into a non-equilibrium steady state (NESS) with non-vanishing currents. Analogously, when detailed balance holds at any instant of time… Expand
