Thermodynamic optimization subsumed in stability phenomena. [PDF]
Sci Rep, 2020 AbstractIn the present paper the possibility of an energetic self-optimization as a consequence of thermodynamic stability is addressed. This feature is analyzed in a low dissipation refrigerator working in an optimized trade-off regime (the so-called Omega function).

Thermodynamic Optimality of Glycolytic Oscillations [PDF]
The Journal of Physical Chemistry B, 2021 Temporal order in living matters reflects the self-organizing nature of dynamical processes driven out of thermodynamic equilibrium. Because of functional reason, the period of a biochemical oscillation must be tuned to a specific value with precision; however, according to the thermodynamic uncertainty relation (TUR), the precision of oscillatory ...

Optimal Thermodynamic Processes For Gases [PDF]
Entropy, 2020 In this paper, we consider an optimal control problem in the equilibrium thermodynamics of gases. The thermodynamic state of the gas is given by a Legendrian submanifold in a contact thermodynamic space. Using Pontryagin’s maximum principle, we find a thermodynamic process in this submanifold such that the gas maximizes the work functional.

Optimal Protocols and Optimal Transport in Stochastic Thermodynamics [PDF]
Physical Review Letters, 2011 Thermodynamics of small systems has become an important field of statistical physics. They are driven out of equilibrium by a control, and the question is naturally posed how such a control can be optimized. We show that optimization problems in small system thermodynamics are solved by (deterministic) optimal transport, for which very efficient ...

Optimal control in stochastic thermodynamics
Journal of Physics Communications, 2023 Abstract We review recent progress in optimal control in stochastic thermodynamics. Theoretical advances provide in-depth insight into minimum-dissipation control with either full or limited (parametric) control, and spanning the limits from slow to fast driving and from weak to strong driving.

Averaged Optimization and Finite-Time Thermodynamics [PDF]
Entropy, 2020 The paper considers typical extremum problems that contain mean values of control variables or some functions of these variables. Relationships between such problems and cyclic modes of dynamical systems are explained and optimality conditions for these modes are found.

Optimization of Stochastic Thermodynamic Machines [PDF]
Journal of Statistical Physics, 2020 The study of stochastic thermodynamic machines is one of the main topics in nonequilibrium thermodynamics. In this study, within the framework of Fokker-Planck equation, and using the method of characteristics of partial differential equation as well as the variational method, performance of stochastic thermodynamic machines is optimized according to ...

Optimal Processes in Irreversible Thermodynamics and Microeconomics [PDF]
Interdisciplinary Description of Complex Systems : INDECS, 2004 This paper describes general methodology that allows one to extend Carnot efficiency of classical thermodynamic for zero rate processes onto thermodynamic systems with finite rate. We define the class of minimal dissipation processes and show that it represents generalization of reversible processes and determines the limiting possibilities of finite ...

Optimal Thermodynamics—New Upperbounds [PDF]
Entropy, 2009 This paper reviews how ideas have evolved in this field from the pioneering work of CARNOT right up to the present. The coupling of thermostatics with thermokinetics (heat and mass transfers) and entropy or exergy analysis is illustrated through study of thermomechanical engines such as the Carnot heat engine, and internal combustion engines.
