Symmetries and nonequilibrium thermodynamics [PDF]
Thermodynamic systems can be defined as composed by many identical interacting subsystems. Here it is shown how the dynamics of relaxation toward equilibrium of a thermodynamic system is closely related to the symmetry group of the Hamiltonian of the subsystems of which it is composed.

Entropy production along nonequilibrium quantum jump trajectories
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 Evolution Thermodynamics of Vacancies [PDF]
An alternative approach - nonequilibrium evolution thermodynamics, is compared with classical Landau approach. A statistical justification of the approach is carried out with help of probability distribution function on an example of a solid with vacancies. Two kinds of kinetic equations are deduced in terms of the internal energy and the modified free

Generalized Clausius inequalities in a nonequilibrium cold-atom system
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 ...

Quantum Thermodynamics: A Nonequilibrium Green's Function Approach [PDF]
peer reviewedWe 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's functions.

Thermodynamics in f(G,T) Gravity
This paper explores the nonequilibrium behavior of thermodynamics at the apparent horizon of isotropic and homogeneous universe model in f(G,T) gravity (G and T represent the Gauss-Bonnet invariant and trace of the energy-momentum tensor, resp.).

Nonequilibrium Thermodynamics of Spacetime [PDF]
It has previously been shown that the Einstein equation can be derived from the requirement that the Clausius relation dS = dQ/T hold for all local acceleration horizons through each spacetime point, where dS is one quarter the horizon area change in Planck units, and dQ and T are the energy flux across the horizon and Unruh temperature seen by an ...

Nonequilibrium thermodynamics of quantum friction [PDF]
Thermodynamic principles are often deceptively simple and yet surprisingly powerful. We show how a simple rule, such as the net flow of energy in and out of a moving atom under nonequilibrium steady state condition, can expose the shortcomings of many popular theories of quantum friction.

Nonequilibrium thermodynamics of turbulence and stochastic fluid systems
Fluid systems are found in the Universe at various scales. Turbulence as a complex form of fluid motion far from thermodynamic equilibrium remains one of the most challenging problems in physics.

Accumulation of Particles and Formation of a Dissipative Structure in a Nonequilibrium Bath
The standard textbooks contain good explanations of how and why equilibrium thermodynamics emerges in a reservoir with particles that are subjected to Gaussian noise.
