Quantum Thermodynamics: A Dynamical Viewpoint
Entropy, 2013 Quantum thermodynamics addresses the emergence of thermodynamic laws from quantum mechanics. The viewpoint advocated is based on the intimate connection of quantum thermodynamics with the theory of open quantum systems. Quantum mechanics inserts dynamics

Compressor Power and Efficiency Optimization: A Finite-Time Thermodynamics Approach [PDF]
EntropyThis paper presents a theoretical optimization of an endoreversible compressor under steady-state conditions. A parametric study using finite-time thermodynamic principles highlights the effect of external irreversibilities on compressor performance.

Linking Optimization Success and Stability of Finite-Time Thermodynamics Heat Engines [PDF]
EntropyIn celebration of 50 years of the endoreversible Carnot-like heat engine, this work aims to link the thermodynamic success of the irreversible Carnot-like heat engine with the stability dynamics of the engine.

Optimal finite-time processes in stochastic thermodynamics [PDF]
Physical Review Letters, 2007 For a small system like a colloidal particle or a single biomolecule embedded in a heat bath, the optimal protocol of an external control parameter minimizes the mean work required to drive the system from one given equilibrium state to another in a ...

Finite-time thermodynamics of fluctuations in microscopic heat engines [PDF]
Physical Review Research, 2022 Fluctuations of thermodynamic quantities become non-negligible and play an important role when the system size is small. We develop finite-time thermodynamics of fluctuations in microscopic heat engines whose environmental temperature and mechanical ...

Entropy, 2012 In this paper, we combine the two universalisms of thermodynamics and dynamical systems theory to develop a dynamical system formalism for classical thermodynamics. Specifically, using a compartmental dynamical system energy flow model we develop a state-

A complementary third law for black hole thermodynamics
European Physical Journal C: Particles and Fields, 2019 There are some examples in the literature, in which despite the fact that the underlying theory or model does not impose a lower bound on the size of black holes, the final temperature under Hawking evaporation is nevertheless finite and nonzero. We show
