The Second Law of Thermodynamics as a Force Law. [PDF]

open access: yesEntropy (Basel), 2018
The second law of thermodynamics states the increase of entropy, Δ S > 0 , for real processes from state A to state B at constant energy from chemistry over biological life and engines to cosmic events.

Thermoelectric Cycle and the Second Law of Thermodynamics. [PDF]

open access: yesEntropy (Basel), 2023
In 2019, Schilling et al. claimed that they achieved the supercooling of a body without external intervention in their thermoelectric experiments, thus arguing that the second law of thermodynamics was bent.

Thermodynamics of Various Entropies in Specific Modified Gravity with Particle Creation

open access: yesAdvances in High Energy Physics, 2018
We consider the particle creation scenario in the dynamical Chern-Simons modified gravity in the presence of perfect fluid equation of state p=(γ-1)ρ. By assuming various modified entropies (Bekenstein entropy logarithmic entropy, power law correction ...

Revisions of the Phenomenological and Statistical Statements of the Second Law of Thermodynamics. [PDF]

open access: yesEntropy (Basel)
The status of the Second Law of Thermodynamics, even in the 21st century, is not as certain as when Arthur Eddington wrote about it a hundred years ago.

A Symmetric Form of the Clausius Statement of the Second Law of Thermodynamics. [PDF]

open access: yesEntropy (Basel)
Bridgman once reflected on thermodynamics that the laws of thermodynamics were formulated in their present form by the great founders of thermodynamics, Kelvin and Clausius, before all the essential physical facts were in, and there has been no adequate ...

Thermodynamics of the FRW Universe at the Event Horizon in Palatini f(R) Gravity

open access: yesAdvances in High Energy Physics, 2018
In an accelerated expanding universe, one can expect the existence of an event horizon. It may be interesting to study the thermodynamics of the Friedmann-Robertson-Walker (FRW) universe at the event horizon.

Bluff Your Way in the Second Law of Thermodynamics [PDF]

open access: yesStudies in History and Philosophy of Science Part B - Studies in History and Philosophy of Modern Physics, 2001
The aim of this article is to analyze the relation between the second law of thermodynamics and the so-called arrow of time. For this purpose, a number of different aspects in this arrow of time are distinguished, in particular those of time-(a)symmetry ...

Thermodynamic Analysis of Gravitational Field Equations in Lyra Manifold [PDF]

open access: yesAdvances in High Energy Physics, 2017
Considering the Einstein field equations in Lyra manifold and applying the unified first law of thermodynamics as well as the Clausius relation to the apparent horizon of FRW universe, we find the entropy of apparent horizon in Lyra manifold. In addition,

Quantum Collapse and the Second Law of Thermodynamics

open access: yesPhysical Review E, 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 ...
