Unified Classical Thermodynamics: Primacy of Dissymmetry over Free Energy

Thermo
In thermodynamic theory, free energy (i.e., available energy) is the concept facilitating the combined applications of the theory’s two fundamental laws, the first and the second laws of thermodynamics.

On the second law of thermodynamics

, 2019
The key purpose of this article is to clarify the foundations of classical statistical mechanics. It is argued that the relevant concepts and laws, e.g.

Study of GSLT in Curvature-Matter Coupling Gravity

EPJ Web of Conferences, 2018
In this work, we study the first and generalized second laws of thermodynamics at the apparent horizon of homogeneous and isotropic universe model in the context of f (G, T) gravity (G and T represent the Gauss-Bonnet invariant and trace of the ...

The mutual co-implication of thermodynamics' first and second laws [PDF]

arXiv, 2004
In classical phenomenological thermodynamics the first and second laws can be regarded as independent statements. Statistical mechanics provides a microscopic substratum that explains thermodynamics in probabilistic terms via a microstate probability distribution ${p_i}$.

The Generalized Second Law of Thermodynamics in Cosmology

, 2000
A classical and quantum mechanical generalized second law of thermodynamics in cosmology implies constraints on the effective equation of state of the universe in the form of energy conditions, obeyed by many known cosmological solutions, and is ...

Quantum Collapse and the Second Law of Thermodynamics

, 2012
A heat engine undergoes a cyclic operation while in equilibrium with the net result of conversion of heat into work. Quantum effects such as superposition of states can improve an engine's efficiency by breaking detailed balance, but this improvement ...

Statistical mechanical derivation of the second law of thermodynamics [PDF]

arXiv, 2000
In a macroscopic (quantum or classical) Hamiltonian system, we prove the second law of thermodynamics in the forms of the minimum work principle and the law of entropy increase, under the assumption that the initial state is described by a general equilibrium distribution.

Infrared Cloaking, Stealth, and the Second Law of Thermodynamics

Entropy, 2012
Infrared signature management (IRSM) has been a primary aeronautical concern for over 50 years. Most strategies and technologies are limited by the second law of thermodynamics.

Violations of the weak cosmic censorship conjecture in the higher dimensional f(R) black holes with pressure

European Physical Journal C: Particles and Fields, 2020
We adopt the energy momentum relation of charged particles to study the thermodynamics laws and weak cosmic censorship conjecture of D-dimensional f(R) AdS black holes in different phase spaces by considering charged particle absorption.

Obtaining Laws of Thermodynamics for Ideal Gases using Elastic Collisions [PDF]

arXiv, 2013
The purpose of this note is to see to what extent ideal gas laws can be obtained from simple Newtonian mechanics, specifically elastic collisions. We present simple one-dimensional situations that seem to validate the laws. The first section describes a numerical simulation that demonstrates the second law of thermodynamics.
