Dynamic Equilibrium Equations in Unified Mechanics Theory

open access: yesApplied Mechanics, 2021
Traditionally dynamic analysis is done using Newton’s universal laws of the equation of motion. According to the laws of Newtonian mechanics, the x, y, z, space-time coordinate system does not include a term for energy loss, an empirical damping term “C”

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 ...

The thermodynamics of the FRW universe in scalar-twist gravitational theories [PDF]

open access: yesIranian Journal of Physics Research, 2020
In this paper, we study the validity of the laws of thermodynamics in the form of a far parallel gravitational theory with an incomplete coupling between curves and scalar fields.

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 ...

Limitations on the Evolution of Quantum Coherences: Towards Fully Quantum Second Laws of Thermodynamics.

open access: yesPhysical Review Letters, 2015
The second law of thermodynamics places a limitation into which states a system can evolve into. For systems in contact with a heat bath, it can be combined with the law of energy conservation, and it says that a system can only evolve into another if ...

Thermodynamic Properties of Spherically-Symmetric, Uniformly-Accelerated Reference Frames [PDF]

open access: yes, 2007
We aim to study the thermodynamic properties of the spherically symmetric reference frames with uniform acceleration, including the spherically symmetric generalization of Rindler reference frame and the new kind of uniformly accelerated reference frame.

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.

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.
