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

open access: yesEntropy, 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, 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
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
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 ...

Gravitational Entropy and the Second Law of Thermodynamics [PDF]

open access: yesEntropy, 2015
The spontaneous violation of Lorentz and diffeomorphism invariance in a phase near the big bang lowers the entropy, allowing for an arrow of time and the second law of thermodynamics. The spontaneous symmetry breaking leads to

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.

Can Quantum Correlations Lead to Violation of the Second Law of Thermodynamics? [PDF]

open access: yesEntropy, 2021
Quantum entanglement can cause the efficiency of a heat engine to be greater than the efficiency of the Carnot cycle. However, this does not mean a violation of the second law of thermodynamics, since there is no local equilibrium for pure quantum states,

On the second law of thermodynamics in modified Gauss–Bonnet gravity [PDF]

open access: green, 2011
The second law and the generalized second law of thermodynamics in cosmology in the framework of the modified Gauss-Bonnet theory of gravity are investigated.
