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

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.

Three-State Quantum Heat Engine Based on Carnot Cycle
Jurnal Fisika Unand, 2020 In this paper,we consider three models of quantum heat engines based on Carnot cycle using three energy levels; (1) the ground state, (2) the degenerate state, and (3) the highest energy state.
