Thermal Contact

open access: yesEntropy, 2008
The concepts of temperature and entropy as applied in equilibrium thermodynamics do not easily generalize to nonequilibrium systems and there are transient systems where thermodynamics cannot apply.

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.

Nonequilibrium Thermodynamics and Scale Invariance

open access: yesEntropy, 2017
A variant of continuous nonequilibrium thermodynamic theory based on the postulate of the scale invariance of the local relation between generalized fluxes and forces is proposed here.

Entropy production along nonequilibrium quantum jump trajectories

open access: yesNew Journal of Physics, 2013
For classical nonequilibrium systems, the separation of the total entropy production into the adiabatic and nonadiabatic contributions is useful for understanding irreversibility in nonequilibrium thermodynamics.

Nonequilibrium thermodynamics of feedback control [PDF]

open access: yesPhysical Review E, 2012
We establish a general theory of feedback control on classical stochastic thermodynamic systems, and generalize nonequilibrium equalities such as the fluctuation theorem and the Jarzynski equality in the presence of feedback control with multiple measurements. Our results are generalizations of the previous relevant works to the situations with general

Generalized Clausius inequalities in a nonequilibrium cold-atom system

open access: yesCommunications Physics, 2023
The Clausius inequality is a way of analysing the entropy of a given process and its routes can be found in the second law of thermodynamics. Here, the authors study the non-equilibrium thermodynamics of an ultracold atomic gas in order to confirm the ...

Physicochemical Mechanics and Nonequilibrium Chemical Thermodynamics

open access: yesEntropy, 2023
Equilibrium thermodynamics answers the question, “by how much?” Nonequilibrium thermodynamics answers the question “how fast?” The physicochemical mechanics approach presented in this article answers both of these questions.

Nonequilibrium thermodynamics of interacting tunneling transport: variational grand potential, density-functional formulation, and nature of steady-state forces

open access: yes, 2012
The standard formulation of tunneling transport rests on an open-boundary modeling. There, conserving approximations to nonequilibrium Green function or quantum-statistical mechanics provide consistent but computational costly approaches; alternatively ...

Nonequilibrium critical scaling from quantum thermodynamics [PDF]

open access: yes, 2016
The emerging field of quantum thermodynamics is contributing important results and insights into archetypal many-body problems, including quantum phase transitions.
