Optimal finite-time Brownian Carnot engine [PDF]
Phys. Rev. E 105, L052103 (2022), 2021 Recent advances in experimental control of colloidal systems have spurred a revolution in the production of mesoscale thermodynamic devices. Functional "textbook" engines, such as the Stirling and Carnot cycles, have been produced in colloidal systems where they operate far from equilibrium.

The Principle of Least Action for Reversible Thermodynamic Processes and Cycles
Entropy, 2018 The principle of least action, which is usually applied to natural phenomena, can also be used in optimization problems with manual intervention. Following a brief introduction to the brachistochrone problem in classical mechanics, the principle of least

The thermodynamics of cognition: A mathematical treatment
Computational and Structural Biotechnology Journal, 2021 There is a general expectation that the laws of classical physics must apply to biology, particularly the neural system. The evoked cycle represents the brain's energy/information exchange with the physical environment through stimulus.

Metal Consumption of Heat Engines and Heat Capacity of their Working Fluids [PDF]
Problems of the Regional Energetics, 2020 Ensuring efficient energy supply in general and heat supply in particular together with creation of air conditioning systems is a very urgent task of modern energy industry, particularly acute in the absence of large centralized energy sources.

Quantum heat engines with Carnot efficiency at maximum power
Physical Review Research, 2022 Heat engines constitute the major building blocks of modern technologies. However, conventional heat engines with higher power yield lesser efficiency and vice versa and respect various power-efficiency trade-off relations.

Efficiency at maximum power of low dissipation Carnot engines [PDF]
, 2010 We study the efficiency at maximum power, $\eta^*$, of engines performing finite-time Carnot cycles between a hot and a cold reservoir at temperatures $T_h$ and $T_c$, respectively.

The myth of the high-efficiency external-combustion Stirling engine [PDF]
, 2015 The reported discrepancy between theory and experiment for external combustion Stirling engines is explained by the addition of thermal resistance of the combustion gasses to the standard Carnot model. In these cases, the Stirling engine ideal efficiency
