Finite-Time Thermodynamics and Complex Energy Landscapes: A Perspective [PDF]

Entropy
Finite-time thermodynamics (FTT) describes the study of thermodynamic processes that take place in finite time. Due to the finite-time requirement, in general the system cannot move from equilibrium state to equilibrium state.

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

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 ...

Compressor Power and Efficiency Optimization: A Finite-Time Thermodynamics Approach [PDF]

Entropy
This 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.

(Finite-Time) Thermodynamics, Hyperbolicity, Lorentz Invariance: Study of an Example [PDF]

Entropy
Our study lies at the intersection of three fields: finite-time thermodynamics, relativity theory, and the theory of hyperbolic conservation laws.

Finite-time thermodynamics of port-Hamiltonian systems [PDF]

Physica D: Nonlinear Phenomena, 2013
In this paper, we identify a class of time-varying port-Hamiltonian systems that is suitable for studying problems at the intersection of statistical mechanics and control of physical systems.

Linking Optimization Success and Stability of Finite-Time Thermodynamics Heat Engines [PDF]

Entropy
In 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.

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
