The Second Law Of Thermodynamics as a Force Law [PDF]

open access: yesEntropy, 2018
The second law of thermodynamics states the increase of entropy, Delta S > 0, for real processes from state A to state B at constant energy from chemistry over biological life and engines to cosmic events. The connection of entropy to information, phase-space and heat is helpful, but does not immediately convince observers of the validity and ...

First and Second Law of Quantum Thermodynamics: A Consistent Derivation Based on a Microscopic Definition of Entropy

open access: yesPRX Quantum, 2021
Deriving the laws of thermodynamics from a microscopic picture is a central quest of statistical mechanics. This tutorial focuses on the derivation of the first and second law for isolated and open quantum systems far from equilibrium, where such ...

The Holographic Model of Dark Energy and Thermodynamics of Non-Flat Accelerated Expanding Universe [PDF]

open access: yes, 2006
Motivated by recent results on non-vanishing spatial curvature \cite{curve} we employ the holographic model of dark energy to investigate the validity of first and second laws of thermodynamics in non-flat (closed) universe enclosed by apparent horizon ...

Quantum Thermodynamics: A Nonequilibrium Green's Functions Approach [PDF]

open access: yes, 2015
We establish the foundations of a nonequilibrium theory of quantum thermodynamics for noninteracting open quantum systems strongly coupled to their reservoirs within the framework of the nonequilibrium Green functions (NEGF). The energy of the system and

Deduction of Lorentz Transformations from Classical Thermodynamics

open access: yesEntropy, 2015
The Lorentz transformations are obtained by assuming that the laws of classical thermodynamics are invariant under changes of inertial reference frames.

The first law of general quantum resource theories [PDF]

open access: yesQuantum, 2020
We extend the tools of quantum resource theories to scenarios in which multiple quantities (or resources) are present, and their interplay governs the evolution of physical systems.

Quantum thermodynamics of the resonant-level model with driven system-bath coupling [PDF]

open access: yes, 2017
We study nonequilibrium thermodynamics in a fermionic resonant level model with arbitrary coupling strength to a fermionic bath, taking the wide-band limit.

Stochastic thermodynamics and hierarchy of fluctuation theorems with multiple reservoirs

open access: yesNew Journal of Physics, 2018
We reformulate stochastic thermodynamics in terms of noise realizations for Langevin systems in contact with multiple reservoirs and investigate the structure of the second laws of thermodynamics.

Fundamental Work Cost of Quantum Processes

open access: yesPhysical Review X, 2018
Information-theoretic approaches provide a promising avenue for extending the laws of thermodynamics to the nanoscale. Here, we provide a general fundamental lower limit, valid for systems with an arbitrary Hamiltonian and in contact with any ...
